Ecclesiastes 5:4-8

4When you make a vow to God, do not delay to fulfill it. He has no pleasure in fools; fulfill your vow.

5It is better not to make a vow than to make one and not fulfill it.

6Do not let your mouth lead you into sin. And do not protest to the temple messenger, “My vow was a mistake.” Why should God be angry at what you say and destroy the work of your hands?

7Much dreaming and many words are meaningless. Therefore fear God.

8If you see the poor oppressed in a district, and justice and rights denied, do not be surprised at such things; for one official is eyed by a higher one, and over them both are others higher still.
