The study of inconsistencies in the Bible has a long history. In the 17th century, Spinoza considered the Bible to be “a book rich in contradictions.” In the 18th century, Thomas Paine in “The Age of Reason” compiled many of the Bible’s self-contradictions. And in 1860, William Henry Burr produced a list of 144 self-contradictions in the Bible. This is an updated list of over 712 inconsistencies in the Bible.
Genesis 21:14 And Abraham rose up early in the morning, and took bread, and a bottle of water, and gave it unto Hagar, putting it on her shoulder, and the child, and sent her away: and she departed, and wandered in the wilderness of Beersheba.15 And the water was spent in the bottle, and she cast the child under one of the shrubs.16 And she went, and sat her down over against him a good way off, as it were a bowshot: for she said, Let me not see the death of the child. And she sat over against him, and lift up her voice, and wept.17 And God heard the voice of the lad; and the angel of God called to Hagar out of heaven, and said unto her, What aileth thee, Hagar? fear not; for God hath heard the voice of the lad where he is.18 Arise, lift up the lad, and hold him in thine hand; for I will make him a great nation.
