Leviticus 27:29

No person who has been set apart for destruction is to be ransomed; he must be put to death.

Then Israel made a vow to the Lord, “If You will deliver this people into our hands, we will completely destroy their cities.”

and then sent you on a mission and said: ‘Go and completely destroy the sinful Amalekites. Fight against them until you have annihilated them.’
