Ecclesiastes 5:2-6

MSTC(i) 2 and let not thine heart speak anything rashly before God. For God is in heaven, and thou upon earth, therefore let thy words be few. 3 For where much carefulness is, there are many dreams: and where many words are, there men may hear fools. 4 If thou make a vow unto God, be not slack to perform it. As for foolish vows, he hath no pleasure in them. 5 If thou promise anything, pay it; for better it is that thou make no vow than that thou shouldest promise, and not pay. 6 Suffer not thy mouth to cause thy flesh for to sin, neither say thou before the angel that it is thy ignorance. For then God will be angry at thy voice, and destroy all the works of thine hands.
