'Sweareth' in the Bible

In whose eyes a vile person is contemned; but he honoureth them that fear the LORD. He that sweareth to his own hurt, and changeth not.

He that hath blameless hands and a pure heart; who lifteth not up his soul unto vanity, nor sweareth deceitfully:

But the king shall rejoice in God; every one that sweareth by him shall glory: but the mouth of them that speak lies shall be stopped.
