'Swearing' in the Bible

Although they say, "As surely as the LORD lives,' still they are swearing falsely."

Swearing, lying, murder, theft, and adultery are rampant, and blood mingles with blood.

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."
