'Mighty men' in the Bible

Your wives, your little ones, and your cattle shall remain in the land which Moses gave you on this side Jordan. But you shall go armed before your brothers, all the mighty men of valor, and help them

And Jehovah said to Joshua, See, I have given Jericho into your hand, and its king, and the mighty men of war.

So Joshua went up from Gilgal, he and all the people of war with him, and all the mighty men of war.
