Jos Joshua, chapter Book of Joshua, chapter 5
And this [is] the cause why Y’hoshua [Yehovah is Salvation] did circumcise: All the people that came out of Mitzrayim [Egypt - The Narrow Place], [that were] males, [even] all the men of war, died in the wilderness by the way, after they came out of Mitzrayim [Egypt - The Narrow Place].Num 14:23
