'Swore' in the Bible

She said to him, “My lord, you swore by the Lord your God to your maidservant, saying, ‘Solomon your son shall certainly be king after me and he shall sit on my throne.’

even as I swore to you by the Lord, the God of Israel, saying, ‘Solomon your son shall certainly be king after me, and he shall sit on my throne in my place’; I will indeed do so this very day.”

And look, you have with you Shimei the son of Gera, the Benjamite of Bahurim; he is the one who cursed me with a sinister curse the day I went to Mahanaim. But he came down to meet me at the Jordan [on my return], and I swore to him by the Lord, saying, ‘I will not put you to death with the sword.’

Then King Solomon swore by the Lord, saying, “May God do the same to me, and more also, if Adonijah has not requested this [deplorable] thing against his own life.
