Ecclesiastes 5:2-5

2Do not be rash with your mouth, And let not your heart utter anything hastily before God. For God is in heaven, and you on earth; Therefore let your words be few.

3For a dream comes through much activity, And a fool’s voice is known by his many words.

4When you make a vow to God, do not delay to pay it; For He has no pleasure in fools. Pay what you have vowed—

5Better not to vow than to vow and not pay.
