A common view in ancient Mesopotamia was that the earth was flat. Abraham came from Ur, a major Sumerian city, before settling in Canaan. The Sumerians and Babylonians ruled in 2000-600 BC, when Moses and many other Biblical writers lived.
Sumerians and Babylonians
The Sumerians and Babylonians are considered some of the most advanced in their era in geology and cosmology:

The American Federation of Teachers website explains that the Sumerians thought that the world was flat:

Cosmology: Did the ancient Sumerians know about our “solar system?”
"In this primeval sea was somehow engendered the universe the 'heaven-earth,' consisting of a vaulted heaven superimposed over a flat earth and united with it." (Kramer, Samuel Noah.
History Begins at Sumer. Garden City: Doubleday Anchor Books, 1959. Pp 76-84.)
"... a vaulted heaven superimposed over a flat earth and united with it..." (Kramer, Samuel Noah.

Was There Ever A Flat Earth Consensus?
This of course is not to say that automatically the Hebrews would accept all the beliefs of their neighbors. Their main difference, however, was in theology and religion rather than science. Major differences included Torah observance and their rejection of idols and of worship of other gods. Even in this area they were not always so different- Egyptians practiced circumcision and some Egyptians like Akhenaton were monotheists, while other Egyptians proposed that the gods were just faces or aspects of the one true God. Even in the Bible there are cases where Egyptians acknowledge God.
Thus, when it came to science, it might not be a surprise if they believed the other scientific teachings of the academics of their era.
Below are some verses that agree with belief in a flat earth:
The earth's circle
A circle (hug) is flat, a ball(dur) is round. eg. Isaiah 22:18 uses the word ball (dur).
Isaiah 40:22 It is he that sitteth upon the circle (hug) of the earth,
Proverbs 8:27 When he prepared the heavens, I was there: when he set a compass (hug) upon the face of the depth:

Matthew 4:8 “Once again, the devil took him to a very high mountain, and showed him all the kingdoms of the world [
cosmos] in their glory.”
The earth's corners
One explanation has been that "corners" is a designation for directions.
Isaiah 11:12 And he shall set up an ensign for the nations, and shall assemble the outcasts of Israel, and gather together the dispersed of Judah from the four corners of the earth.
Rev 7:1 And after these things I saw four angels standing on four corners of the earth, holding the four winds of the earth, that the wind should not blow on the earth, nor on the sea, nor on any tree.
The earth's foundations
Job 9:6 Which shaketh the earth out of her place, and the pillars thereof tremble.
Job 38:4 Where wast thou when I laid the foundations of the earth?
Job 38:6 Whereupon are the foundations thereof fastened? or who laid the corner stone thereof
1 Samuel 2:8 for the pillars of the earth are the Lord's, and he hath set the world upon them.

The earth's stretching out
Something that is stretched out is flat.

Stretching a line across the eartth, rather than around it
Job 38:44 Who marked off its dimensions? Surely you know! Who stretched a measuring line across it?
The earth's stretching over nothing
Something that is suspended over nothing would have an underside.
Job 26:7 He stretcheth out the north over the empty place,
and hangeth the earth upon nothing [
beliymah].
The earth's form is like clay under a seal.
A seal is a two dimensional object that stamps another two dimensional one on clay.
Job 38:13-14
That it might take hold of the ends of the earth, And the wicked be shaken out of it?
It takes on form like clay under a seal, And stands out like a garment.
