Ecclesiastes 5:4-6

21st Century King James Version

⁴ 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.

⁵ Better is it that thou shouldest not vow, than that thou shouldest vow and not pay.

⁶ Let not thy mouth cause thy flesh to sin, neither say thou before God’s angel that the vow was an error. Why should God be angry at thy voice, and destroy the work of thine hands?
