'Take Oaths' in the Bible

Give ear to this, O family of Jacob, you who are named by the name of Israel, and have come out of the body of Judah; who take oaths by the name of the Lord, and make use of the name of the God of Israel, but not truly and not in good faith.

And it will be that, if they give their minds to learning the ways of my people, using my name in their oaths, By the living Lord; as they have been teaching my people to take oaths by the Baal; then their place will be made certain among my people.

And the worshippers of the army of heaven on the house-tops, and the Lord's worshippers who take oaths by Milcom,

But most of all, my brothers, do not take oaths, not by the heaven, or by the earth, or by any other thing: but let your Yes be Yes, and your No be No: so that you may not be judged.
