Numbers 10:10-12

10Also in the day of your gladness, in your appointed feasts, and at the beginning of your months, you shall blow the trumpets over your burnt offerings and over the sacrifices of your peace offerings; and they shall be a memorial for you before your God: I am the Lord your God.”

11Now it came to pass on the twentieth day of the second month, in the second year, that the cloud was taken up from above the tabernacle of the Testimony.

12And the children of Israel set out from the Wilderness of Sinai on their journeys; then the cloud settled down in the Wilderness of Paran.
