Contradiction with Genesis 6:7
This verse contradicts Genesis 15:5 because in Genesis 6:7, God intends to destroy mankind, whereas in Genesis 15:5, God promises Abram numerous descendants.
Genesis 6:7: And the LORD said, I will destroy man whom I have created from the face of the earth; both man, and beast, and the creeping thing, and the fowls of the air; for it repenteth me that I have made them. [both...: Heb. from man unto beast]
Contradiction with Jeremiah 18:7-10
This passage shows God's willingness to change plans based on human actions, contradicting the unconditional promise of numerous descendants to Abram in Genesis 15:5.
Jeremiah 18:7-10: [At what] instant I shall speak concerning a nation, and concerning a kingdom, to pluck up, and to pull down, and to destroy [it];
Paradox #1
Genesis 15:5 discusses the promise of countless descendants. A contradiction could be the literal interpretation of too many descendants for a single person, which challenges biological constraints and population growth models.
