Ecclesiastes 5:4-6

Leeser(i) 4 (5:3) When thou makest a vow unto God, do not delay to pay it; for he hath no pleasure in such fools: that which thou hast vowed must thou pay. 5 (5:4) It is better that thou shouldst not vow, than that thou shouldst vow and not pay. 6 (5:5) Suffer not thy mouth to cause thy body to sin; and say thou not before the messenger, that it was an error: wherefore should God be angry because of thy voice, and destroy the work of thy hands?
