'Oath' in the Bible

For thus says the Lord Yahweh: I will also deal with you as you have done, who have despised the oath in breaking the covenant.

and he took of the seed royal, and made a covenant with him; he also brought him under an oath, and took away the mighty of the land;

As I live, says the Lord Yahweh, surely in the place where the king dwells who made him king, whose oath he despised, and whose covenant he broke, even with him in the midst of Babylon he shall die.

For he has despised the oath by breaking the covenant; and behold, he had given his hand, and yet has done all these things; he shall not escape.

Therefore thus says the Lord Yahweh: As I live, surely my oath that he has despised, and my covenant that he has broken, I will even bring it on his own head.
