Now go, attack the Amalekites and totally destroy all that belongs to them. Do not spare them; put to death men and women, children and infants, cattle and sheep, camels and donkeys.

The LORD said to Moses, 2 Take vengeance on the Midianites for the Israelites. After that, you will be gathered to your people. ...They fought against Midian, as the LORD commanded Moses, and killed every man. 8 ... The Israelites captured the Midianite women and children and took all the Midianite herds, flocks and goods as plunder....Moses was angry with the officers of the armythe commanders of thousands and commanders of hundredswho returned from the battle. 15 Have you allowed all the women to live? he asked them. 16 They were the ones who followed Balaams advice and enticed the Israelites to be unfaithful to the LORD in the Peor incident, so that a plague struck the LORDs people. 17
