“All those who were listed of the Levites, whom Moses and Aaron and the chiefs of Israel listed, by their clans and their fathers’ houses, from thirty years old up to fifty years old, everyone who could come to do the service of ministry and the service of bearing burdens in the tent of meeting, those listed were 8,580. According to the commandment of the Lord through Moses they were listed, each one with his task of serving or carrying. Thus they were listed by him, as the Lord commanded Moses” (Numbers 4:46-49, ESV).
The Book of Numbers begins at Mount Sinai, where the Israelites have received their laws and covenant from God. Now God has taken up residence among them in the Tabernacle that resides in the middle of their encampment. As they sojourn through the wilderness to take possession of the Promised Land, it will be a major logistical undertaking to mobilize, move and secure the Tabernacle at each layover along their journey.
