“2. The Nazarites having made this vow were no more to serve God as they liked, but were bound |414| to follow the law appointed by God for Nazarites (Num. 6); their eating, drinking, and sacrifice were appointed of God, which lets us see that albeit God will have voluntary service, yet He will have no will worship, but all His service done according to His special command. No uncommanded service will please God.”
