Deuteronomy 19:11 MSG

[11] On the other hand, if a man with a history of hatred toward his neighbor waits in ambush, then jumps him, mauls and kills him, and then runs to one of these cities, that’s a different story. The elders of his own city are to send for him and have him brought back. They are to hand him over to the avenger of blood for execution. Don’t feel sorry for him. Clean out the pollution of wrongful murder from Israel so that you’ll be able to live well and breathe clean air.
