King James Version (KJV)
Behold, this day thine eyes have seen how that the LORD had delivered thee to day into mine hand in the cave: and {some} bade {me} kill thee: but {mine eye} spared thee; and I said, I will not put forth mine hand against my lord; for he {is} the LORD'S anointed.
Modern English
Behold, today your eyes have seen how Yahweh had delivered you today into my hand in the cave. Some urged me to kill you; but I spared you; and I said, I will not stretch out my hand against my lord; for he is Yahweh’s anointed.
Hebrew
