Ecclesiastes 5:4-6

Common English Bible

⁴ When you make a promise to God, fulfill it without delay because God has no pleasure in fools. Fulfill what you promise. ⁵ Better not to make a promise than to make a promise without fulfilling it. ⁶ Don’t let your mouth make a sinner of you, and don’t say to the messenger: “It was a mistake!” Otherwise, God may become angry at such talk and destroy what you have accomplished.
