Numbers 35:31 Moreover ye shall take no satisfaction for the life of a murderer, which is guilty of death: but he shall be surely put to death.
God gave the death penalty for anyone who intentionally and with premeditation would murder someone. There would be no exceptions. Second degree murder was time away from family land in the city of refuge. He had to stay there till the high priest died.
God wants us to show great respect for human life. You can’t just call it an accident if you had hate in your heart. If you killed with a weapon or had threatened before.
We should all consider the value of life for the unborn, the old, the sick, and the handicapped. We should respect life!
