You must not feel sorry for him. He was guilty of killing an innocent person. You must remove that guilt from Israel. Then everything will go well for you.
{“Punishment must be as severe as the crime.} Don’t feel sorry about punishing a person that does wrong. If a person takes a life, then he must pay with his own life. The rule is: an eye for an eye, a tooth for a tooth, a hand for a hand, a foot for a foot.
The Lord your God will put these nations under your power. And you will defeat them. You must destroy them completely. Don’t make an agreement with them. Don’t show them mercy.
