Ecclesiastes 5:4-6

CAB^{(i) 4} Whenever you shall vow a vow to God, defer not to pay it; for He has no pleasure in fools. Pay, therefore, whatsoever you have vowed. ⁵ It is better that you should not vow, than that you should vow and not pay. ⁶ Do not allow your mouth to lead your flesh to sin; and say not in the presence of God, It was an error; lest God be angry at your voice, and destroy the works of your hands.
