Contradiction with Exodus 12:48
Exodus 12:48 states that no uncircumcised person shall eat the Passover meal, potentially conflicting with Genesis 17:27 which includes people from Abraham’s household, whether circumcised or not, among those living under his covenant.
Exodus 12:48: And when a stranger shall sojourn with thee, and will keep the passover to the LORD, let all his males be circumcised, and then let him come near and keep it; and he shall be as one that is born in the land: for no uncircumcised person shall eat thereof.
