If you promise a gift to the Lord your God, be careful to bring the gift soon. If you do not bring it, that is a sin. And the Lord will certainly demand it. But if you do not promise to do anything, that will not be a sin. Deuteronomy 23:21-22
「你向耶和華－你的上帝許願，償還不可遲延；因為耶和華－你的上帝必定向你追討，你不償還就有罪。 你若不許願，倒無罪。 申命記 23:21-22
