Ecclesiastes 5:3-4

³If you are continually thinking and worrying about things, you will have bad dreams about them and not rest well. And the more you talk, the more likely it will be that you will say things that are foolish.

⁴When you solemnly promise God that you will do something, do not be foolish by delaying in doing it, because God is not pleased with foolish people. Do all the things that you promise God that you will do.
