'Swear' in the Bible

Though a harlot thou art, O Israel, Let not Judah become guilty, And come not ye in to Gilgal, nor go up to Beth-Aven, Nor swear ye, Jehovah liveth.

They have spoken words, To swear falsehood in making a covenant, And flourished as a poisonous herb hath judgment, on the furrows of a field.
