'Swears' in the Bible

Or if someone swears rashly to do what is good or evil—concerning anything a person may speak rashly in an oath—without being aware of it, but later recognizes it, he incurs guilt in such an instance.

or finds something lost and lies about it; or swears falsely about any of the sinful things a person may do—

or anything about which he swears falsely. He must restore it in full and add one fifth to it; he must give it to its owner when he is found guilty.
