2. James 5:12
But above all, my brothers, do not swear, either by heaven or by earth or by any other oath, but let your "yes" be yes and your "no" be no, so that you may not fall under condemnation.

3. MacArthur
Fallen men are basically inveterate liars. Children lie to their parents and parents lie to their children. Husbands lie to their wives and wives lie to their husbands. People lie to their employers who in turn lie to them and often to the public. Politicians lie to get elected and continue to lie once they are in office…

4. MacArthur
… People lie to the government – perhaps most notably on their income tax returns. Educators lie, Scientists lie, and members of the media lie. Our society is built on a framework of lies, leading one to wonder whether our social structure would survive if everyone were forced to speak the truth for even one day.

5. Matthew 12:34-35
You brood of vipers! How can you speak good, when you are evil? For out of the abundance of the heart the mouth speaks. The good person out of his good treasure brings forth good, and the evil person out of his evil treasure brings forth evil

6. John 8:44
You are of your father the devil, and your will is to do your father's desires. He was a murderer from the beginning, and does not stand in the truth, because there is no truth in him. When he lies, he speaks out of his own character, for he is a liar and the father of lies

7. Proverbs 12:22
Lying lips are an abomination to the LORD, But those who deal faithfully are His delight.
