Ecclesiastes 5:2-4

New Revised Standard Version Catholic Edition

^2 [a] Never be rash with your mouth, nor let your heart be quick to utter a word before God, for God is in heaven, and you upon earth; therefore let your words be few.

³ For dreams come with many cares, and a fool’s voice with many words.

⁴ When you make a vow to God, do not delay fulfilling it; for he has no pleasure in fools. Fulfill what you vow.
