'Swore' in the Bible

She said to him, "My lord, you swore by Yahweh your God to your handmaid, 'Assuredly Solomon your son shall reign after me, and he shall sit on my throne.'

The king swore, and said, "As Yahweh lives, who has redeemed my soul out of all adversity,

most certainly as I swore to you by Yahweh, the God of Israel, saying, 'Assuredly Solomon your son shall reign after me, and he shall sit on my throne in my place;' most certainly so will I do this day."

"Behold, there is with you 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 swore to him by Yahweh, saying, 'I will not put you to death with the sword.'

Then king Solomon swore by Yahweh, saying, "God do so to me, and more also, if Adonijah has not spoken this word against his own life.
