When thou vowest a vow unto God, defer not to pay it; for he hath no pleasure in fools: pay that which thou hast vowed.Better is it that thou shouldest not vow, than that thou shouldest vow and not pay.Suffer not thy mouth to cause thy flesh to sin; neither say thou before the angel, that it was an error: wherefore should God be angry at thy voice, and destroy the work of thine hands? – Ecclesiastes _____________________________When you make a vow to God, do not delay to fulfill it. He has no pleasure in fools; fulfill your vow. It is better not to make a vow than to make one and not fulfill it. Do 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? – Ecclesiastes
