Joshua 5:3-5

Amplified Bible, Classic Edition

³ So Joshua made knives of flint and circumcised the sons of Israel at Gibeath-haaraloth.

⁴ And this is the reason Joshua circumcised them: all the males of the people who came out of Egypt, all the men of war, had died in the wilderness on the way after they came out of Egypt.

⁵ Though all the people who came out were circumcised, yet all the people who were born in the wilderness on the way after Israel came out of Egypt had not been circumcised.
