Numbers 10:12 KJV

10Also in the day of your gladness, and in your solemn days, 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; that they may be to you for a memorial before your God: I am the LORD your God.

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

12And the children of Israel took their journeys out of the wilderness of Sinai; and the cloud rested in the wilderness of Paran.

13And they first took their journey according to the commandment of the LORD by the hand of Moses.

14In the first place went the standard of the camp of the children of Judah according to their armies: and over his host was Nahshon the son of Amminadab.
