Ecclesiastes 5:5-7

Young's Literal Translation

⁵ Better that thou do not vow, than that thou dost vow and dost not complete.

⁶ Suffer not thy mouth to cause thy flesh to sin, nor say before the messenger, that `it [is] an error,' why is God wroth because of thy voice, and hath destroyed the work of thy hands?

⁷ For, in the abundance of dreams both vanities and words abound; but fear thou God.
