Ecclesiastes 5:4-6 If thou make a vow unto God, be not slack to perform it. As for foolish vows, he hath no pleasure in them.

MSTC⁽ⁱ⁾ 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.
