'Swore' in the Bible

She replied, “My lord, you swore to your servant by the Lord your God, ‘Your son Solomon is to become king after me, and he is the one who is to sit on my throne.’

The king swore an oath and said, “As the Lord lives, who has redeemed my life from every difficulty,

just as I swore to you by the Lord God of Israel: Your son Solomon is to become king after me, and he is the one who is to sit on my throne in my place, that is exactly what I will do this very day.”

“Keep an eye on Shimei son of Gera, the Benjaminite from Bahurim who is with you. He uttered malicious curses against me the day I went to Mahanaim. But he came down to meet me at the Jordan River, and I swore to him by the Lord: ‘I will never kill you with the sword.’
