'Men of War' in the Bible

Thirty-eight years had gone by from the time when we came away from Kadesh-barnea till we went over the stream Zered; by that time all the generation of the men of war among us were dead, as the Lord had said.

So when death had overtaken all the men of war among the people,

At that time I gave you orders, saying, The Lord has given you this land for your heritage: all the men of war are to go over armed before your brothers the children of Israel.
