Contradiction with Exodus 20:24
This verse instructs the building of altars made of earth for sacrifices but does not specify animals like Genesis 15:9.
Exodus 20:24: An altar of earth thou shalt make unto me, and shalt sacrifice thereon thy burnt offerings, and thy peace offerings, thy sheep, and thine oxen: in all places where I record my name I will come unto thee, and I will bless thee.
Contradiction with Hebrews 10:4
This verse states that it is not possible for the blood of bulls and goats to take away sins, contrary to the sacrificial practice suggested in Genesis 15:9.
Hebrews 10:4: For [it is] not possible that the blood of bulls and of goats should take away sins.
Contradiction with Hosea 6:6
God desires mercy and not sacrifice, which contrasts with the sacrificial instruction given in Genesis 15:9.
Hosea 6:6: For I desired mercy, and not sacrifice; and the knowledge of God more than burnt offerings.
Contradiction with Isaiah 1:11
God expresses no delight in burnt offerings, contrasting the detailed sacrifice requirements in Genesis 15:9.
Isaiah 1:11: To what purpose [is] the multitude of your sacrifices unto me? saith the LORD: I am full of the burnt offerings of rams, and the fat of fed beasts; and I delight not in the blood of bullocks, or of lambs, or of he goats. [he goats: Heb. great he goats]
Paradox #1
The contradiction or conflict in Genesis 15:9 could be seen in the command to sacrifice animals, which might conflict with the idea of kindness to living beings or the belief that a loving God wouldn't require such acts. Some might see a tension between reverence for life and the act of animal sacrifice.
