'Oaths' in the Bible

Fear the LORD your God, serve him, and make your oaths in his name.

That way, you will not mingle with those nations that remain among you, nor mention the name of their gods, nor make oaths by them, nor serve them, nor worship them.

"Listen to this, house of Jacob, you who are called by the name of Israel, and who have come forth from Judah's loins; you who swear oaths in the name of the LORD and invoke the God of Israel but not in truth, nor in good faith.

Those who have been swearing oaths by the sin of Samaria, or who say, "As your god lives, Dan"' or who say, "As the way of Beer-sheba lives"' will fall, and will never rise again."
