Joshua 5:4-6

Darby Translation

⁴ And this is the cause why Joshua circumcised [them]: all the people that had come out of Egypt, the males, all the men of war, had died in the wilderness on the way, after they came out of Egypt.

⁵ For all the people that came out were circumcised; but all the people that were born in the wilderness on the way, after they came out of Egypt, [them] had they not circumcised.

⁶ For the children of Israel had walked forty years in the wilderness, till the whole nation of men of war had perished who had come out of Egypt, who had not hearkened to the voice of Jehovah; to whom Jehovah had sworn that he would not show them the land which Jehovah had sworn unto their fathers that he would give us, a land flowing with milk and honey.
