I don’t mean to brag, but I don’t think the Nazarite vow would be that hard for me. That’s not because of some high-and-mighty religious leanings, but just because I’ve looked at the requirements for a while now, and I think I could handle it.
No drinking? Check.
No close proximity to death? Check (hopefully).
No haircuts? I’ve always wanted to grow my hair out anyways, so that would give me an excuse. Check.
If that were it, I think I could probably fulfill a Nazarite vow with very little problem. And to be fair, it seems like lots of people in Bible times took this vow up to completion. In Acts 21:23, the Christians casually tell Paul they have four men who took a vow. Paul knows what that means, because in Acts 18:18, he himself had just finished a vow.
But we all know that simple law-keeping isn’t exactly the same as fulfilling the spirit of the vow itself. It’s not just that you keep from certain things—it’s what you’re doing instead that matters. What are you giving your attention to? Why are you restricting yourself like this?
God’s statement in Numbers 6:21 reflects this little bit of oomph at the end of the Nazarite vow. Once you’ve completed your year of devotion and paid your sacrifices, you can also set aside more according to “what you can afford.”
Technically, this is nothing more than a freewill offering, which is completely voluntary. You can give more or you can not. The choice is completely up to you.
Realistically, if you were a “man of substance”, it was expected that you would give more that what was technically required. Moreover, even if you weren’t the one taking the Nazarite vow yourself, if you were wealthy, it was customary to pay the added devotions of poorer members of society that did take the Nazarite vow.
This is the context for the conversation with Paul about the four men taking the vow in Acts 21:23. They ask Paul to cover the expenses of the Nazarites—not because Paul was flush with cash, but because doing so would prove himself to the Jewish accusers who wanted to paint Paul as an anti-Temple heretic.
According to Josephus, King Agrippa even did this as a goodwill measure upon returning to Jerusalem. This may have been more of a calculated political move on his part, but the fact that he did it shows the assumed responsibilities of those more fortunate than others.
But none of that really matters for the specific context of what’s at stake here. Taking a Nazarite vow was already a voluntary expression of devotion and loyalty to Jehovah. Why would you not also give more on the backend to show even more appreciation to Him?
We may not do this today, but I’m still amazed at how often God gives people in the Old Testament opportunities to grow deeper in their faith. You didn’t have to be a priest or a Levite to be close to God; all it took was a genuine desire to be in His presence.
And if that’s what you wanted, the Nazarite vow was there for the taking. And more.
