'Sweareth' in the Bible

Or when a person sweareth, speaking wrongfully with the lips to do evil, or to do good, even anything which man speaketh wrongfully with an oath, and it hath been hid from him; -- when he hath known then he hath been guilty of one of these;

or all that concerning which he sweareth falsely, he hath even repaid it in its principal, and its fifth he is adding to it; to him whose it is he giveth it in the day of his guilt-offering.
