Numbers 8 - 10

Chapter 8 - All the Levites are sanctified for service to the Lord, and they are called out as a tribe in belonging to God, in substitution for every firstborn male throughout Israel.

Chapter 9 - Israel celebrates the first Passover after leaving Egypt. The nation camps or moves, based upon the presence of God on the Tabernacle of meeting. When His presence rises above the Tabernacle, they break camp and follow where He leads, and when His presence rests upon the Tabernacle they stay encamped where they are.

Chapter 10 - A pair of silver trumpets are crafted for communicating messages to the tribes, and the leaders of the tribes. The presence of the Lord rises up, the nation breaks camp, and the tribes follow the cloud of the Lord in departing from Sinai, and in traveling towards the promised land
