'Swear' in the Bible

And the priest hath caused her to swear, and hath said unto the woman, If no man hath lain with thee, and if thou hast not turned aside to uncleanness under thy husband, be free from these bitter waters which cause the curse;

(then the priest hath caused the woman to swear with an oath of execration, and the priest hath said to the woman) -- Jehovah doth give thee for an execration, and for a curse, in the midst of thy people, in Jehovah's giving thy thigh to fall, and thy belly to swell,

Have I conceived all this people, have I brought them forth, that thou sayest to me, Carry them in thy bosom, as the nursing-father beareth the suckling, unto the land which thou didst swear unto their fathers?

shall in no wise see the land which I did swear unto their fathers: none of them that despised me shall see it.

I swear that none of you will enter the land I promised to settle you in, except Caleb son of Jephunneh and Joshua son of Nun.

I, Yahweh, have spoken. I swear that I will do this to the entire evil community that has conspired against Me. They will come to an end in the wilderness, and there they will die.”

If a man vow a vow unto the LORD, or swear an oath to bind his soul with a bond; he shall not break his word, he shall do according to all that proceedeth out of his mouth.
