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