'Oath' in the Bible

For thus saith the Lord Jehovah: I will also deal with thee as thou hast done, who hast 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, saith the Lord Jehovah, surely in the place where the king dwelleth that made him king, whose oath he despised, and whose covenant he brake, even with him in the midst of Babylon he shall die.

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

Therefore thus saith the Lord Jehovah: As I live, surely mine oath that he hath despised, and my covenant that he hath broken, I will even bring it upon his own head.
