Numbers 6:2  (King James Version)
Speak unto the children of Israel, and say unto them, When either man or woman shall separate themselves to vow a vow of a Nazarite, to separate themselves unto the LORD:

Numbers 6:5 Numbers 6:6 ; Exodus 33:16 ; Leviticus 20:26 ; Proverbs 18:1 ; Romans 1:1 ; 2 Corinthians 6:16 ; Galatians 1:15
Hebrews 7:27

separate themselves
The word {yaphli,} rendered "shall separate themselves," signifies, "the doing of something extraordinary," and is the same word as is used concerning the making a singular vow. ( Leviticus 27:2 );it seems to convey the idea of a person's acting
from extraordinary zeal for God and religion.* to vow.
Le 27:2 Jud 13:5 1Sa 1:28 Am 2:11,12 Lu 1:15 Ac 21:23,24

to separate themselves
or, to make themselves Nazarites.
{Lahazzir,} from {nazar,} to be separate; hence {nazir,} a Nazarite, i
e., a person separated; one peculiarly devoted to the service of God by being separated from all servile employments. The Nazarites were of two kinds: such as were devoted to God by their parents in their infancy, or even sometimes before they were born; and such as devoted themselves. The former were Nazarites for life; and the latter commonly bound themselves to observe the laws of the Nazarites for a limited time. The Nazarites for life were not bound to the same strictness as the others, concerning whom the laws relate.
