Ecclesiastes 5:2-5

Think before you speak, and be careful about what you say to God. God is in heaven, and you are on the earth, so say only a few words to God. The saying is true: Bad dreams come from too much worrying, and too many words come from foolish people. 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. It is better not to promise anything than to promise something and not do it.
