ASV Genesis 12:7 And Jehovah appeared unto Abram, and said, Unto thy seed will I give this land: and there builded he an altar unto Jehovah, who appeared unto him.
Like this verse, there are a number of verses throughout the Bible where we read that Yahweh appeared to someone. We also read that Moses talked with Yahweh "face to face" (Exodus 33:11) and Adam and Eve heard the sound of Yahweh when he was walking in the garden. (Genesis 3:8).
And they saw the God of Israel; and there was under his feet as it were a pavement of sapphire stone, like the very heaven for clearness. (Exodus 24:10, RSV)
This verse is pretty self-explanatory, they "saw" the Elohim of Israel. Later we will show that Yahweh is the "Elohim of Israel" in contrast to the Elohim of the other nations.
The LORD is a man of war; the LORD is his name. (Exodus 15:3, KJV)
It can easily be argued that the use of the word "man" here is figurative and not literal, but as we showed previously, in Genesis 18 we found that one of the three men that came to Abraham was Yahweh and he was identified as a “man.”
If Yahweh is a physical being, then can he be omniscient (all knowing), omnipresent (all present) and omnipotent (all powerful)?
...and the man and his wife hid themselves from the presence of Jehovah God amongst the trees of the garden. And Jehovah God called unto the man, and said unto him, Where art thou (Genesis 3:8-9, ASV)
If Yahweh was omnipresent, then there would be no place one could go where Yahweh was not, but here we see that Adam and Eve hid themselves from Yahweh, evidently a place where Yahweh was not. We can also see that Yahweh was no omniscient as he had to ask them where they were.
And Jehovah repenteth that He hath made man in the earth, and He grieveth Himself--unto His heart. And Jehovah saith, "I wipe away man whom I have prepared from off the face of the ground, from man unto beast, unto creeping thing, and unto fowl of the heavens, for I have repented that I have made them." (Genesis 6:6-7, YLT)
Repentance implies an admission of an incorrect action. Yahweh admits that he made a mistake.
And Jehovah came down to see the city and the tower, which the children of men builded. (Genesis 11:5, ASV)
Here we see that Yahweh is not omnipresent because Yahweh had to "come down" to see the city to see what was going on. We also know that he was not omniscient because he had to go see what was going on, he did not already know.
And Moses returned unto Jehovah, and said, Lord, wherefore hast thou dealt ill with this people? why is it that thou hast sent me? (Exodus 5:22, ASV)
If Moses "returns" to Yahweh then he evidently was somewhere where Yahweh was not. If Yahweh is everywhere, you would not be able to be away from his presence and then return to it.
Unto a land flowing with milk and honey: for I will not go up in the midst of thee; for thou art a stiffnecked people: lest I consume thee in the way. (Exodus 33:3, KJV)
If Yahweh was omnipresent, how could Israel go anywhere without Yahweh being with them?
And Jehovah was with Judah; and drove out the inhabitants of the hill-country; for he could not drive out the inhabitants of the valley, because they had chariots of iron. (Jdg 1:19)
According to this verse, Yahweh was "with" Judah implying that by Yahweh's power, possibly through Judah, he drove out the inhabitants of the hill country. But interestingly Yahweh was powerless to drive out the inhabitants of the valley because of their iron chariots.
 Some translations have "voice," but this Hebrew word literally means "sound."
