'Departure' in the Bible

Later, they left Elim, and the whole congregation of the Israelis came to the desert of Sin, which lay between Elim and Sinai, on the fifteenth day of the second month after their departure from the land of Egypt.

Joshua circumcised them because all of the males among the people who came out of Egypt that is, all the warriors had died during their journey through the wilderness following their departure from Egypt.

Although everyone who had left Egypt had been circumcised, nevertheless all the people born during the journey after their departure from Egypt had not been circumcised.
