Ecclesiastes 5:2-5

2Don’t make rash promises, and don’t be hasty in bringing matters before God. After all, God is in heaven, and you are here on earth. So let your words be few.

3Too much activity gives you restless dreams; too many words make you a fool.

4When you make a promise to God, don’t delay in following through, for God takes no pleasure in fools. Keep all the promises you make to him.

5It is better to say nothing than to make a promise and not keep it.
