Ecclesiastes 5:4-6

New Century Version

⁴ If you make a promise to God, don’t be slow to keep it. God is not happy with fools, so give God what you promised. ⁵ It is better not to promise anything than to promise something and not do it. ⁶ Don’t let your words cause you to sin, and don’t say to the priest at the Temple, “I didn’t mean what I promised.” If you do, God will become angry with your words and will destroy everything you have worked for.
