Numbers 10:10

10 You must also blow the trumpets when you are happy. Blow them at your appointed feasts. Blow them at your New Moon Feasts. Blow them when you sacrifice your burnt offerings. Blow them when you sacrifice your friendship offerings. They will remind me of you. I am the LORD your God."

Numbers 10:10 In-Context

8 "The sons of Aaron, the priests, must blow the trumpets. That is a law for you and your children after you for all time to come.
9 Suppose you go into battle in your own land. And suppose it is against an enemy who is beating you down. Then blow a blast on the trumpets. If you do, I will remember you. I will save you from your enemies. I am the LORD your God.
10 You must also blow the trumpets when you are happy. Blow them at your appointed feasts. Blow them at your New Moon Feasts. Blow them when you sacrifice your burnt offerings. Blow them when you sacrifice your friendship offerings. They will remind me of you. I am the LORD your God."
11 It was the 20th day of the second month of the second year. On that day the cloud began to move. It went up from above the holy tent where the tablets of the covenant were kept.
12 Then the people of Israel started out from the Desert of Sinai. They traveled from place to place. They kept going until the cloud came to rest in the Desert of Paran.
