'Rash' in the Bible

“But if she marries while under her vows or if she has bound herself by a rash statement,

But if her husband disapproves of her [making her vow or pledge] on the day that he hears of it, then he shall annul her vow which she is under and the rash statement of her lips by which she bound herself; and the Lord will forgive her.

“For now it would be heavier than the sand of the sea;Therefore my words have been incoherent,

Do not be hasty with your mouth [speaking careless words or vows] or impulsive in thought to bring up a matter before God. For God is in heaven and you are on earth; therefore let your words be few.

The heart (mind) of those who act impulsively will discern the truth,And the tongue of the stammerers will hurry to speak clearly.

I will stand at my guard postAnd station myself on the tower;And I will keep watch to see what He will say to me,And what answer I will give [as His spokesman] when I am reproved.
