'Lips' in the Bible

"If {she has a husband} while bound by her vows or a rash promise of her lips,

But if on the day her husband hears [of it], he forbids her, then he will nullify her vow that she is under, and the rash promise of her lips that she bound on herself; and Yahweh will forgive her.

But if her husband nullified them on the day he hears [them], all her vows going out of her lips concerning her vows or the pledge on herself will not stand; her husband has nullified them, and Yahweh will forgive her.
