Deuteronomy 23:21-23

21WhenH834 thou vowest a vow to Jehovah thy 1GodH430, thou shalt not delay to perform it; for Jehovah thy 2GodH430 will certainly require it of thee, and it shall be sin in thee.

22But if thou forbear to vowH5088, it shall beH1961 no sinH2399 in thee.

23What isH1961 gone out of thy lips thou shalt keep and do, as thou hast vowedH5087 to Jehovah thy 3God, the voluntary-offering that thou hast promised with thy mouth.
