Joshua 5:2-9
2At that time Yahweh said to Joshua, “Make for yourself aflint knives and circumcise again the sons of Israel the second time.” 3So Joshua made himself flint knives and circumcised the sons of Israel at 1Gibeath-haaraloth. 4Now this is the reason why Joshua circumcised them: aall the people who came out of Egypt who were males, all the men of war, died in the wilderness along the way when they came out of Egypt. 5For all the people who came out were circumcised, but all the people who were born in the wilderness along the way as they came out of Egypt had not been circumcised. 6For the sons of Israel had walked aforty years in the wilderness, until all the nation, that is, the men of war who came out of Egypt, were completely destroyed because they did not listen to the voice of Yahweh, bto whom Yahweh had sworn that He would not let them see the land which Yahweh had sworn to their fathers to give us, a land flowing with milk and honey. 7And their sons whom He raised up in their place, Joshua 1circumcised; for they were uncircumcised because they had not circumcised them along the way.
