'Lips' in the Bible

"If she is [married] to a husband, while her vows are on her, or the rash utterance of her lips, with which she has bound her soul,

But if her husband disallow her in the day that he hears it, then he shall make void her vow which is on her, and the rash utterance of her lips, with which she has bound her soul: and Yahweh will forgive her.

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.
