'Swear' in the Bible

Go and get thee in unto king David, and say unto him, Didst not thou, my lord, O king, swear unto thine handmaid, saying, Assuredly Solomon thy son shall reign after me, and he shall sit upon my throne? why then doth Adonijah reign?

And it was told Solomon, saying, Behold, Adonijah feareth king Solomon: for, lo, he hath caught hold on the horns of the altar, saying, Let king Solomon swear unto me to day that he will not slay his servant with the sword.

And lo, with thee is Shimei son of Gera, the Benjamite of Bahurim, and he reviled me -- a grievous reviling -- in the day of my going to Mahanaim; and he hath come down to meet me at the Jordan, and I swear to him by Jehovah, saying, I do not put thee to death by the sword;

And now, as the Lord lives, the One who established me, seated me on the throne of my father David, and made me a dynasty as He promised—I swear Adonijah will be put to death today!”

And the king sent and called for Shimei, and said unto him, Did I not make thee to swear by the LORD, and protested unto thee, saying, Know for a certain, on the day thou goest out, and walkest abroad any whither, that thou shalt surely die? and thou saidst unto me, The word that I have heard is good.

If any man trespass against his neighbour, and an oath be laid upon him to cause him to swear, and the oath come before thine altar in this house:

As the Lord your God lives, there is no nation or kingdom where my lord has not sent someone to search for you. When they said, ‘He is not here,’ he made that kingdom or nation swear they had not found you.

But the king said to him, “How many times must I make you swear not to tell me anything but the truth in the name of Yahweh?”
