'Swears' in the Bible

or when a person swears an oath, speaking thoughtlessly with his lips, whether to do evil or to do good, with regard to anything which the individual might speak thoughtlessly in an oath, even if he did not realize it, but he himself has later come to know it and is guilty with regard to one of these oaths --

or has found something lost and denies it and swears falsely concerning any one of the things that someone might do to sin --

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.
