Joshua 5:3-5

New Living Translation

³ So Joshua made flint knives and circumcised the entire male population of Israel at Gibeath-haaraloth.^[a]

⁴ Joshua had to circumcise them because all the men who were old enough to fight in battle when they left Egypt had died in the wilderness. ⁵ Those who left Egypt had all been circumcised, but none of those born after the Exodus, during the years in the wilderness, had been circumcised.
