Leviticus 26:7

And ye shall chase your enemies
Who being overcome in battle, and put to the flight, should be pursued: and they shall fall before you by the sword;
not by the sword of one another, as the Midianites did, ( Judges 7:21 Judges 7:22 ) , so Jarchi; but rather by the sword of the Israelites, for oftentimes multitudes of the enemy are killed in a pursuit.
