This is the law of the Nazarite, when he hath vowed his oblation to the Lord in the time of his consecration, besides those things which his hand shall find, according to that which he had vowed in his mind, so shall he do for the fulfilling of his sanctification.
Numbers 6:19 And shall take the boiled shoulder of the ram, and one unleavened cake out of the basket, and one unleavened wafer, and he shall deliver them into the hands of the Nazarite, after his head is shaven.
Numbers 6:20 And receiving them again from him, he shall elevate them in the sight of the Lord: and they being sanctified shall belong to the priest, as the breast, which was commanded to be separated, and the shoulder. After this the Nazarite may drink wine.
Numbers 6:21 This is the law of the Nazarite, when he hath vowed his oblation to the Lord in the time of his consecration, besides those things which his hand shall find, according to that which he had vowed in his mind, so shall he do for the fulfilling of his sanctification.
Numbers 6:22 And the Lord spoke to Moses, saying:
Numbers 6:23 Say to Aaron and his sons: Thus shall you bless the children of Israel, and you shall say to them:
The verse centers on "nazarite", "hath", "vowed", "oblation", "lord", "time", "consecration", and "besides". It is saying that the verse draws attention to "nazarite" and "hath", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 20's "And receiving them again from him he..." into verse 22's "And the Lord spoke to Moses saying...", so "nazarite" and "hath" belong inside that flow. In Numbers context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "nazarite" and "hath" with trust shaped by these words, not by a vague optimism outside the passage.
