And wherefore hath the LORD brought us unto this land, to fall by the sword, that our wives and our children should be a prey? were it not better for us to return into Egypt?

For the Amalekites and the Canaanites are there before you, and ye shall fall by the sword: because ye are turned away from the LORD, therefore the LORD will not be with you.

Anyone in the open field who touches a person who has been killed by the sword or has died, or who even touches a human bone, or a grave, will be unclean for seven days.

They killed the kings of Midian in addition to the ones they had slain: Evi and Rekem and Zur and Hur and Reba, the five kings of Midian; they also killed Balaam son of Beor by the sword.
