Chapter 9: Commanded to Keep the Passover
Israel is again commanded to keep the Passover. We also learn again, that the congregation of Israel moved when the cloud descended upon them and they journeyed every time the cloud went up. (Numbers 9:17-21)
Chapter 10: Ark of the Covenant
The Lord speaks to Moses and commands him to make two trumpets, for the purpose of calling the assembly for the journeying of the camps of Israel. The trumpets will be used not only for assembly but for calling the princes of each tribe to gather together and to sound the alarm for war.
In the 20th day of the second year the cloud lifted up and the children of Israel took their journeys out of the wilderness of Sinai and the cloud rested in the wilderness of Paran.
Each tribe with their standard was lifted as they marched forth in a prescribed order. The Ark of the Covenant, however always went before them.
