God described a special vow for anyone who chose to set themselves apart for Him, called a nazirite vow, a promise to live with extra separation for a time. During that time they avoided wine and anything from grapes, did not cut their hair, and stayed away from dead bodies, even close family. If someone died suddenly near them, they shaved on the seventh day, and on the eighth brought two turtledoves or two pigeons; they also brought a first-year lamb, and the earlier days of the vow did not count.
When the vow was completed, the person came to the entrance of the Tent of Meeting with offerings: a male lamb, a ewe lamb, a ram, and a basket of unleavened cakes and wafers, with grain offerings and libations. After shaving, the hair was placed on the fire under the sacrifice.
God taught Aaron and his sons to bless Israel: “God bless you and protect you… and grant you peace.”
When Moses finished setting up and anointing the Tabernacle, the tribal leaders brought gifts, six carts and twelve oxen. Moses gave two carts and four oxen to the Gershonites, four carts and eight oxen to the Merarites, and none to the Kohathites, who carried sacred items on their shoulders. Then, for twelve days, one leader each day brought offerings to dedicate the altar, beginning with Nahshon of Judah. When Moses entered the Tent of Meeting, he heard God’s voice speaking from above the Ark’s cover, between the cherubim.
