My word-for-word translation: not - to be clear, free, innocent - Jehovah - to lift, take - who - name - emptiness, vanity

My conversational translation: Jehovah will not free those who use His name with empty meaning.

Not sure why I felt the need to research this one verse so thoroughly. I put it into my own translations just to clarify in my own head what it means to me. It seems to indicate serious consequences if we are not using His name with the honor and respect He deserves. Every time we use a name of God it should be done so with reverence, never lightly tossed about.
