Joshua 5:4-6

21st Century King James Version

⁴ And this is the cause why Joshua did circumcise: All the people who came out of Egypt who were males, even all the men of war, died in the wilderness by the way after they came out of Egypt.

⁵ Now all the people who came out were circumcised; but all the people who were born in the wilderness on the way as they came forth out of Egypt, them they had not circumcised.

⁶ For the children of Israel walked forty years in the wilderness till all the people who were men of war, who came out of Egypt, were consumed because they obeyed not the voice of the Lord. Unto these the Lord swore that He would not show them the land which the Lord swore unto their fathers that He would give us, a land that floweth with milk and honey.
