Numbers 35
Bible in Basic English (BBE)
21 Or in hate gave him blows with his hand, causing death; he who gave the death-blow is to be put to death; he is a taker of life: he whose right it is to give punishment for blood may put to death the taker of life when he comes face to face with him.
King James Version (KJV)
21 Or in enmity smite him with his hand, that he die: he that smote him shall surely be put to death; for he is a murderer: the revenger of blood shall slay the murderer, when he meeteth him.
