'Oath' in the Bible

then the priest shall cause the woman to swear with the oath of cursing, and the priest shall tell the woman, "Yahweh make you a curse and an oath among your people, when Yahweh allows your thigh to fall away, and your body to swell;

When a man vows a vow to Yahweh, or swears an oath to bind his soul with a bond, he shall not break his word; he shall do according to all that proceeds out of his mouth.

"If she vowed in her husband's house, or bound her soul by a bond with an oath,

Every vow, and every binding oath to afflict the soul, her husband may establish it, or her husband may make it void.
