8 The trumpets are to be blown by Aaron's sons, the priests.“The following rule is to be observed for all time to come.
9 When you are at war in your land, defending yourselves against an enemy who has attacked you, sound the signal for battle on these trumpets. I, the Lord your God, will help you and save you from your enemies.
10 Also on joyful occasions — at your New Moon Festivals and your other religious festivals — you are to blow the trumpets when you present your burnt offerings and your fellowship offerings. Then I will help you. I am the Lord your God.”
11 On the twentieth day of the second month in the second year after the people left Egypt, the cloud over the Tent of the Lord's presence lifted,
12 and the Israelites started on their journey out of the Sinai Desert. The cloud came to rest in the wilderness of Paran.
13 They began to march at the command of the Lord through Moses,
14 and each time they moved, they were in the same order. Those under the banner of the division led by the tribe of Judah started out first, company by company, with Nahshon son of Amminadab in command.
