Números 35

He whose right it is to give punishment for blood, may himself put to death the taker of life when he comes face to face with him.

El pariente del muerto, él matará al homicida: cuando lo encontrare, él le matará.

The revenger of blood himself shall slay the murderer: when he meeteth him, he shall slay him.

The avenger of blood shall himself put the murderer to death. When he meets him, he shall put him to death.
