'During' in the Bible

When the priests who carried the ark entered the Jordan River, as their feet touched the water's edge (The Jordan River overflows all of its banks daily during the harvest season.),

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.

As a result, it was their descendants, whom he raised up to take their place, that Joshua circumcised. They had remained uncircumcised, because they had not been circumcised during their journey.

While the Israelis remained encamped at Gilgal on the plains of Jericho, they observed the Passover during the evening of the fourteenth day of the month.
