Deuteronomy 23:21-23

21When thou shalt vowH5087 a vowH5088 unto YhwhH3068 thy GodH430, thou shalt not slackH309 to payH7999 it: for YhwhH3068 thy GodH430 will surelyH1875 requireH1875 it of thee; and it would be sinH2399 in thee. 22But if thou shalt forbearH2308 to vowH5087, it shall be no sinH2399 in thee. 23That which is gone outH4161 of thy lipsH8193 thou shalt keepH8104 and performH6213; even a freewill offeringH5071, according as thou hast vowedH5087 unto YhwhH3068 thy GodH430, which thou hast promisedH1696 with thy mouthH6310.
