Yehoshua 5:4-6

Orthodox Jewish Bible

⁴ And this is the reason why Yehoshua did the Bris Milah: Kol HaAm that came out of Mitzrayim, that were zekharim (males), even Kol Anshei HaMilchamah, died in the midbar baderech, after they came out of Mitzrayim.

⁵ Now Kol HaAm that came out were Mulim (circumcised); but Kol HaAm that were born in the midbar baderech when they came forth out of Mitzrayim, them they had not given Bris Milah.

⁶ For the Bnei Yisroel walked arba’im shanah in the midbar, until Kol HaGoy that were Anshei HaMilchamah, which came out of Mitzrayim, were consumed, because they obeyed not the Kol Hashem (voice of Hashem); unto whom Hashem swore that He would not show them HaAretz, which Hashem swore unto their Avot that He would give us, Eretz zavat cholov u’devash.
