'Sware' in the Bible

And the king sware, and said, As Jehovah liveth, who hath redeemed my soul out of all adversity,

verily as I sware unto thee by Jehovah, the God of Israel, saying, Assuredly Solomon thy son shall reign after me, and he shall sit upon my throne in my stead; verily so will I do this day.

And, behold, there is with thee Shimei the son of Gera, the Benjamite, of Bahurim, who cursed me with a grievous curse in the day when I went to Mahanaim; but he came down to meet me at the Jordan, and I sware to him by Jehovah, saying, I will not put thee to death with the sword.

Then king Solomon sware by Jehovah, saying, God do so to me, and more also, if Adonijah hath not spoken this word against his own life.
