Josua 5:4

Orsaken till att Josua omskar dem var denna: Alla män som hade dragit ut ur Egypten, alla stridsdugliga män, hade dött under ökenvandringen efter uttåget ur Egypten.

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