'Swear' in the Bible

and thou shalt in truth, in justice, and in righteousness swear, As Jehovah liveth! and the nations shall bless themselves in him, and in him shall they glory.

And if they say, As Jehovah liveth! surely they swear falsely.

Wherefore should I pardon thee? Thy children have forsaken me, and swear by them that are not God. I have satiated them, and they have committed adultery, and they troop to the harlots' house.

What? steal, murder, and commit adultery, and swear falsely, and burn incense unto Baal, and walk after other gods whom ye know not ...

And it shall come to pass, if they will diligently learn the ways of my people, to swear by my name, As Jehovah liveth even as they taught my people to swear by Baal they shall be built up in the midst of my people.
