'Men of War' in the Bible

This is the reason why Joshua circumcised them: all the people who came out of Egypt who were males, all the men of war, died in the wilderness along the way after they came out of Egypt.

For the sons of Israel walked forty years in the wilderness, until all the nation, that is, the men of war who came out of Egypt, perished because they did not listen to the voice of the Lord, to whom the Lord had sworn that He would not let them see the land which the Lord had sworn to their fathers to give us, a land flowing with milk and honey.

You shall march around the city, all the men of war circling the city once. You shall do so for six days.

When they brought these kings out to Joshua, Joshua called for all the men of Israel, and said to the chiefs of the men of war who had gone with him, “Come near, put your feet on the necks of these kings.” So they came near and put their feet on their necks.
