'Bond' in the Bible

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.

"Also when a woman vows a vow to Yahweh, and binds herself by a bond, being in her father's house, in her youth,

and her father hears her vow, and her bond with which she has bound her soul, and her father holds his peace at her; then all her vows shall stand, and every bond with which she has bound her soul shall stand.

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

and her husband heard it, and held his peace at her, and didn't disallow her; then all her vows shall stand, and every bond with which she bound her soul shall stand.

But if her husband made them null and void in the day that he heard them, then whatever proceeded out of her lips concerning her vows, or concerning the bond of her soul, shall not stand: her husband has made them void; and Yahweh will forgive her.
