Ecclesiastes 5:2-6

2Be not rash with thy mouth, and let not thy heart be hasty to utter any thing before God: for God is in heaven, and thou upon earth: therefore let thy words be few.1 3For a dream cometh through the multitude of business; and a fool’s voice is known by a multitude of words.

4When thou vowest a vow to God, defer not to pay it; for he hath no pleasure in fools: pay that which thou hast vowed. 5Better is it that thou shouldest not vow, than that thou shouldest vow and not pay. 6Permit not thy mouth to cause thy flesh to sin; neither say thou before the angel, that it was an error: why should God be angry at thy voice, and destroy the work of thy hands?
