Numbers 5:21; Numbers 30:2; Numbers 30:13

21 Then the priest shall charge the woman with an oath of cursing, and the priest shall say unto the woman, The LORD make thee a curse and an oath among thy people, when the LORD doth make thy thigh to rot, and thy belly to swell;

2 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.

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