'Oath' in the Bible

For thus saith the Lord GOD; I will even deal with thee as thou hast done, which hast despised the oath in breaking the covenant.

And hath taken of the king's seed, and made a covenant with him, and hath taken an oath of him: he hath also taken the mighty of the land:

As I live, saith the Lord GOD, 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.

Seeing he despised the oath by breaking the covenant, when, lo, he had given his hand, and hath done all these things, he shall not escape.

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