'Lips' in the Bible

“However, if she should marry while under her vows or the rash statement of her lips by which she has bound herself,

But if on the day her husband hears of it, he forbids her, then he shall annul her vow which she is under and the rash statement of her lips by which she has bound herself; and the Lord will forgive her.

But if her husband indeed annuls them on the day he hears them, then whatever proceeds out of her lips concerning her vows or concerning the obligation of herself shall not stand; her husband has annulled them, and the Lord will forgive her.
