'Rash' 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.
