Contradiction with Exodus 12:40
Genesis 15:14 mentions that the descendants will be enslaved and mistreated for 400 years, while Exodus 12:40 states they lived in Egypt for 430 years.
Exodus 12:40: Now the sojourning of the children of Israel, who dwelt in Egypt, [was] four hundred and thirty years.
Contradiction with Acts 7:6
Genesis 15:14 states the nation will be judged, but Acts 7:6 says the nation in which they are enslaved will judge them.
Acts 7:6: And God spake on this wise, That his seed should sojourn in a strange land; and that they should bring them into bondage, and entreat [them] evil four hundred years.
Paradox #1
Genesis 15:14 talks about God's promise to punish the nation that enslaves Abram's descendants and how they will leave with great possessions. The potential contradiction arises when considering the nature of God as both just and merciful. Some people might find it inconsistent that God would allow the Israelites to be enslaved in the first place, or question why God would allow suffering before delivering them. This can lead to discussions about why a benevolent and omnipotent God allows hardship for His chosen people, which some see as inconsistent with His qualities of justice and mercy.
Paradox #2
The contradiction or conflict might arise from the idea of punishing people who may not be directly responsible for the actions of their leaders or ancestors. This can raise questions about justice and fairness, as it seems to involve collective punishment.
