'Swear Falsely' in the Bible

And though they say, As LORD lives, surely they swear falsely.

Will ye steal, murder, and commit adultery, and swear falsely, and burn incense to Baal, and walk after other gods that ye have not known,

Again, ye have heard that it was said to them in old times, Thou shall not swear falsely, but shall render to the Lord thine oaths.
