'Oath' in the Bible

If a man sin against his neighbour, and an oath be laid upon him to make him swear, and the oath come before thine altar in this house;

They took an oath to the Lord in a loud voice, with shouting, with trumpets, and with rams’ horns.

And all Judah rejoiced at the oath: for they had sworn with all their heart, and sought him with their whole desire; and he was found of them: and the LORD gave them rest round about.

And the king said to him, Have I not, again and again, put you on your oath to say nothing to me but what is true in the name of the Lord?

And he also rebelled against king Nebuchadnezzar, who had made him take oath by God; and he stiffened his neck, and hardened his heart from returning to Jehovah the God of Israel.
