Numbers 10:10-12

10Also in the day of your gladness, and in your set feasts, and in the beginnings of your months, ye shall blow with the trumpets over your burnt offerings, and over the sacrifices of your peace offerings; and they shall be to you for a memorial before your God: I am the LORD your God.

11And it came to pass in the second year, in the second month, on the twentieth day of the month, that the cloud was taken up from over the tabernacle of the testimony.

12And the children of Israel set forward according to their journeys out of the wilderness of Sinai; and the cloud abode in the wilderness of Paran.
