If a man or a woman takes an oath to keep himself separate and give himself to the Lord

Christians should be like Jesus, true Nazarites

Say to the children of Israel, If a man or a woman takes an oath to keep himself separate and give himself to the Lord;
Numbers 6:2

Totally devoted to God and separated from the things of this world, having the special blessing of God.

May the Lord send his blessing on you and keep you:
May the light of the Lord’s face be shining on you in grace:
May the Lord’s approval be resting on you and may he give you peace.
So they will put my name on the children of Israel, and I will give them my blessing. Num 6:24-27
