Ecclesiastes 5:2-6

ECB(i) 2 Neither terrify with your mouth nor hasten with your heart to utter a word at the face of Elohim; for Elohim is in the heavens - and you on earth; so be of few words. 3 The dream comes by the abundance of drudgery; and the voice of a fool by the abundance of words. 4 When you vow a vow to Elohim, defer not to shalam; for he delights not in fools: shalam your vow. 5 Better not to vow, than to vow and not shalam. 6 Neither give your mouth that your flesh sin; nor say at the face of the angel, An inadvertent error! Why enrage Elohim at your voice and despoil the work of your hands?
