4 so that Jehovah doth establish His word which He spake unto me, saying, If thy sons observe their way to walk before Me in truth, with all their heart, and with all their soul; saying, There is not cut off a man of thine from the throne of Israel.
4
and that the LORD may keep his promise to me: ‘If your descendants watch how they live, and if they walk faithfully before me with all their heart and soul, you will never fail to have a successor on the throne of Israel.’
