1 Kings 2:43

He was guilty both of rebellion against the express, and just, and (as himself called it) good command of the king, and of perjury against God; which were two high and heinous crimes. His oath he calls the oath of the Lord, because it was taken in God's presence, and he was called upon as a witness of it, and as the avenger of all violations of it, and because the law of God obliged him to the performance of it.
