Who knows better what God meant by what God said than God. When Jesus speaks on the meaning of the Scriptures you have the Living Word explaining the Written Word. It does not get any more authoritative than that. Jesus said, Thou shalt do no murder, . . . The sixth commandment is not a blanket statement ordering men never to take the life of another.
Murder is the taking of innocent life.
We have snow, dusting, white out, blizzard, white stuff, flurry, sleet, hail, freezing rain. The Eskimos have over 100. Even though both blizzard and flurry mean it will snow, they do not mean the same thing. In Hebrew there are 9 different words that mean to cause the death of another. But they do not all mean the same thing.
