Joshua 5:2–6

2At that time Jehovah said unto Joshua, Make thee knives of flint, and circumcise again the children of Israel the second time. 3And Joshua made him knives of flint, and circumcised the children of Israel at the hill of the foreskins. 4And this is the cause why Joshua did circumcise: all the people that came forth out of Egypt, that were males, even all the men of war, died in the wilderness by the way, after they came forth out of Egypt. 5For all the people that came out were circumcised; but all the people that were born in the wilderness by the way as they came forth out of Egypt, they had not circumcised. 6For the children of Israel walked forty years in the wilderness, till all the nation, even the men of war that came forth out of Egypt, were consumed, because they hearkened not unto the voice of Jehovah: unto whom Jehovah sware that he would not let them see the land which Jehovah sware unto their fathers that he would give us, a land flowing with milk and honey.
