What does Numbers 35:21 mean?

or in enmity smote him with his hand, so that he died; he that smote him shall surely be put to death; he is a murderer: the avenger of blood shall put the murderer to death, when he meeteth him.

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.

or in enmity smote him with his hand, so that he died; he that smote him shall surely be put to death; he is a murderer: the avenger of blood shall put the murderer to death, when he meeteth him.

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.

or in enmity he hath smitten him with his hand, and he dieth; the smiter is certainly put to death; he <FI>is<Fi> a murderer; the redeemer of blood doth put the murderer to death in his coming against him.

Or being his enemy, strike him with his hand, and he die: the striker shall be guilty of murder: the kinsman of him that was slain as soon as he findeth him, shall kill him.

or from enmity smite him with his hand, so that he die, he that smote him shall certainly be put to death; he is a murderer: the avenger of blood shall put the murderer to death, when he meeteth him. —
