Joshua 5:4-6

⁴And this is the way in which Joshua purified the children of Israel; as many as were born in the way, and as many as were uncircumcised of them that came out of Egypt,

⁵all these Joshua circumcised; for forty and two years Israel wondered in the wilderness of Mabdaris—

⁶Therefore most of the fighting men that came out of the land of Egypt, were uncircumcised, who disobeyed the commands of God; concerning whom also he determined that they should not see the land, which the Lord sware to give to their fathers, even a land flowing with milk and honey.
