Deuteronomy 23:21-23

Wycliffe Bible

²¹ When thou makest a vow to thy Lord God, thou shalt not tarry to yield it, for thy Lord God shall ask that of thee; and if thou tarriest, it shall be reckoned to thee into sin. (When thou makest a vow to the Lord thy God, thou shouldest not delay in fulfilling it, for the Lord thy God shall ask for that of thee; and if thou delayest, it shall be reckoned unto thee as a sin.)

²² If thou wilt not promise, thou shalt be without sin. (If thou maketh no vow, thou hast not sinned.)

²³ Forsooth thou shalt keep (thy word), and do that that went out once of thy lips, as thou promisedest to thy Lord God, and hast spoken with thine own will and thy mouth. (But once thy vow hath gone out of thy lips, thou shalt keep thy word, and do it, as thou promisedest to the Lord thy God, and hast spoken with thy own will and thy own mouth.)
