2nd Commandment

We should not abuse the name of God by using it to swear.

40.  Deuteronomy 10:20.  You shall fear the Lord your God and serve him, you shall cling to him and make your oaths in his name.

41.  Hezekiel 17:19.  As surely as I live, says the Lord, I will bring down on his head my oath which has has despised, and my covenant which he has broken.

42.  Matthew 5:34,37.  But I say to you, that you should not swear at all.  Let your speech simply be like this:  let your "yes" be "yes" and your "no" be "no".  Anything beyond this from evil.
