Numbers 30:5 CPDV

³  If any man makes a vow to the Lord, or binds himself by an oath, he shall not make his word null and void, but all that he has promised, he shall fulfill.

⁴  If a woman, who is in her father's house, vows anything, or binds herself by an oath, and she is still in a state of childhood, if her father knew of the vow which she has promised or of the oath by which she has obligated her soul, and he kept silent, she shall be liable to the vow:

⁵  whatever she has promised or swore, she shall complete in deed.

⁶  But if her father, as soon as he had heard it, had contradicted it, both her vows and her oaths shall be nullified, neither shall she be held liable to the promise, because her father had contradicted it.

⁷  If she has a husband, and she has vowed anything, then, once the word has gone out of her mouth, she will have obligated her soul by an oath.
