Is The Hebrew God Omniscient?

Regarding God knowing the past, present, and future, the bible is ambiguous about whether God is omniscient or not.
(1) Example in favor of the omniscience of God: “Before I formed you in the womb I knew you, before you were born I set you apart; I appointed you as a prophet to the nations (Jeremiah 1:5)."
(2) A counter-example denying the omniscience of God: In the book of Job, God had no prior knowledge of Job’s suffering that Job was about to experience, to the extent that Satan MOVED God to give Job suffering that God had never even considered before Satan had caused him to do it: “And the LORD said unto Satan, Hast thou considered my servant Job, that there is none like him in the earth, a perfect and an upright man, one that feareth God, and escheweth evil? and still he holdeth fast his integrity, although thou MOVEDST me against him, to destroy him without cause (Job 2:3)."
So as you can see, you have to proof-text certain passages in the bible to claim God is omniscient (knowing everything in the past, present, and future), while ignoring and suppressing other texts that speak against God being omniscient.

Apart from the example I gave from Job, there are many biblical passages that suggest God is not omniscient.
As has been discussed elsewhere on the Patheos family of blogs, there is an interesting tradition found in many biblical texts that affirms that Yahweh, the God of Israel, genuinely consults with others and considers their voice despite the fact that he is eminently more powerful and knowledgeable than they. This is especially evident in those texts where Yahweh reasons or dialogues with a prophet and, at times, even changes his intended course of action after hearing their argument(s) and opinion(s). As one example, consider Exodus 32.7-14 (NRSV) which records a dialogue between Yahweh and Moses after the people of Israel–whom Yahweh had just powerfully delivered from the land of Egypt–worshiped and offered sacrifices to a golden calf:
The Lord said to Moses, ‘Go down at once! Your people, whom you brought up out of the land of Egypt, have acted perversely; they have been quick to turn aside from the way that I commanded them; they have cast for themselves an image of a calf, and have worshipped it and sacrificed to it, and said, “These are your gods, O Israel, who brought you up out of the land of Egypt!" ’ The Lord said to Moses, ‘I have seen this people, how stiff-necked they are. Now let me alone, so that my wrath may burn hot against them and I may consume them; and of you I will make a great nation.
But Moses implored the Lord his God, and said, ‘O Lord, why does your wrath burn hot against your people, whom you brought out of the land of Egypt with great power and with a mighty hand? Why should the Egyptians say, “It was with evil intent that he brought them out to kill them in the mountains, and to consume them from the face of the earth"? Turn from your fierce wrath; change your mind and do not bring disaster on your people. Remember Abraham, Isaac, and Israel, your servants, how you swore to them by your own self, saying to them, “I will multiply your descendants like the stars of heaven, and all this land that I have promised I will give to your descendants, and they shall inherit it for ever." ’ And the Lord changed his mind about the disaster that he planned to bring on his people.
Here Yahweh is depicted as very angry with Israel and intends to “consume" them and to raise up a “great nation" from Moses instead; but Moses pleads with Yahweh to “turn" from his anger and to not destroy the people of Israel since the Egyptians would deride the situation, and because Yahweh had made special promises to Israel’s progenitors.
Consider further Isaiah 38.1-6 (NRSV), which reads:
In those days Hezekiah became sick and was at the point of death. The prophet Isaiah son of Amoz came to him, and said to him, ‘Thus says the Lord: Set your house in order, for you shall die; you shall not recover.’ Then Hezekiah turned his face to the wall, and prayed to the Lord: ‘Remember now, O Lord, I implore you, how I have walked before you in faithfulness with a whole heart, and have done what is good in your sight.’ And Hezekiah wept bitterly.
Then the word of the Lord came to Isaiah: ‘Go and say to Hezekiah, Thus says the Lord, the God of your ancestor David: I have heard your prayer, I have seen your tears; I will add fifteen years to your life. I will deliver you and this city out of the hand of the king of Assyria, and defend this city
Here the prophet Isaiah prophesies in the name of Yahweh that the king of Israel, Hezekiah, will die. However, after Hezekiah entreats Yahweh, Yahweh spares his life and again sends Isaiah to change his original prophesy.
Consider also Gen. 18.20-21 (NRSV):
Then the Lord said, ‘How great is the outcry against Sodom and Gomorrah and how very grave their sin! I must go down and see whether they have done altogether according to the outcry that has come to me; and if not, I will know.’
Here it is stated the Yahweh must descend down from his heavenly abode to determine whether or not to inflict judgment upon Sodom and Gomorrah based on the report that he has received.
Further, in the famous chapter of Genesis 22 where we read the story about Abraham’s intention to sacrifice his son Isaac upon an altar according to a commandment that he had received from God, we read verses 9-13 (NRSV) that:
When they came to the place that God had shown him, Abraham built an altar there and laid the wood in order. He bound his son Isaac, and laid him on the altar, on top of the wood. Then Abraham reached out his hand and took the knife to kill his son. But the angel of the Lord called to him from heaven, and said, ‘Abraham, Abraham!’ And he said, ‘Here I am.’ He said, ‘Do not lay your hand on the boy or do anything to him; for now I know that you fear God, since you have not withheld your son, your only son, from me.’ And Abraham looked up and saw a ram, caught in a thicket by its horns. Abraham went and took the ram and offered it up as a burnt-offering instead of his son.
Here it is stated that only after Abraham raises his arm to perform the deed does Yahweh truly know that he (Abraham) fears God.
Thus although it is clear that some biblical passages state that God knows our thoughts (consider, for instance, 1 Chronicles 28.9, which reads “And you, my son Solomon, know the God of your father, and serve him with single mind and willing heart; for the Lord searches every mind, and understands every plan and thought."), it is also clear that some biblical passages, such as those discussed above, also portray God as genuinely learning and changing his intended course(s) of action.
So, as I said, you have to arbitrarily pick and choose which bible verses to focus on in order to make the argument that God is omniscient (and to ignore the parts of the bible that imply God isn’t omniscient).

Good points, but true believers always cherry pick the parts of the Bible that support their ideologies.

John, the way I understand the evolution of faith based religions, it started with knowledge. The people of knowledge were known as the Gods. The term god meant knowledge. What we understand today about that area of history was passed down to us in pre-history by the Vegas. Vega is a term that means knowledge. Then the most successful god was RA. RA’s power was in controlling all the knowledge. RA transferred this knowledge by sunlight to you. Then Jesus came along and was Gnostic. Gnostic means knowledge. In the churches and bibles you must have seen Jesus standing on a cloud omitting light. That is a Gnostic cloud. When enough knowledge gathers in one place it forms a cloud that omits knowledge to you. A gnostic cloud of knowledge. To the people of the time, Jesus standing on a gnostic cloud meant that he was a teacher (Buda) of knowledge.
The way I would look at your posting is that Jeremiah was talking about the power of the deity. His thinking was the deity god was formed in the manner of the thinking of the Egyptian gods. And Job was also talking about a deity but in the ways of thinking by the Greeks and northern countries.
Jeremiah was born in 655 BC and died in Egypt.
Job was from Edom, now part of Jordan. Job lived to be 280 years old. Job lived after Joseph but before Moses (after 1650 BC and before 1500 BC).
Point being, I think you are trying to pigeon hole and define god. Faith based belief does not work that way and the bible was not written with that in mind.

(1) Example in favor of the omniscience of God: “Before I formed you in the womb I knew you, before you were born I set you apart; I appointed you as a prophet to the nations (Jeremiah 1:5)."

Well no. You're not talking about reality of course but just some passages changed umpteen times in a very old story about fictional characters. You might as well be talking about whether Harry Potter had this versus that power based on this or that passage of the set of HP books. Whether there actually was a Harry Potter is a different thing entirely. The problem is, we allow people to treat the bible as if it was NOT fiction, or at best an extremely inaccurate telling of some folk tales. We allow them to treat it as some kind of historical recounting. It really isn't, or like I said, at best just an extremely thin retelling.

The verses you cited, along with many others, can be combined to easily make the case that each writer is not writing about the same god, let alone that god is omniscient. That god is not aware of what it will do in the future, whether it’s a few minutes or a few centuries. It seems very unaware of local politics, let alone where the world is going.

With an attitude like that we'll never figure out how many angels can dance on the head of a pin.

At times, Jesus certainly thought the future was open, not determined for an omniscient God, such as we see in the terrified prayer Jesus makes in the Garden of Gethsemane where Jesus petitions God to change his plan so that Jesus wouldn’t have to die: " ‘Abba, Father,’ He said, ‘all things are possible for You. Take this cup from Me. Yet not what I will, but what You will.’ (Mark 14:36)." Here Jesus does not seem to think God is privy to a predetermined future.

Just as Moses argued against God about killing the infidels who had broken the commandments they hadn't seen yet. Or how Jacob wrestled with God. And Abraham got to save a couple people from Sodom. Or Hezekiah, but nobody has ever heard of him, so who cares?

Of course the biblical god is not omniscient. The bible has proven that over and over again. The biblical god is not omniscient, not benevolent and not omnipotent. The bible proves that, too. He is none of those things because he is a figment of many people’s imagination, and nothing more. If you think the biblical god is anything other than that, we await your objective evidence with bated breath.

This. ^^^ Although I think (hard to tell, because the didn't state his point) the OP was trying to point out that believers ignore the contradictions about their god's omniscience. Ultimately, though, the argument is moot because their god is a myth.
