Ecclesiastes 5:2-5

2You should not speak too soon. Think carefully before you make a promise to God. God is in heaven and you are here on the earth. So do not say too much.

3If you worry about many things, you will have many dreams. If you talk too much, you will say foolish things.

4If you make a promise to God, quickly do what you have promised. God is not pleased with foolish people. So give what you have promised to give.

5It is better not to promise anything than to promise something and then not do it.
