Numbers 10:12

9 And if ye go to war in your land against the enemy that oppresseth you, then ye shall blow an alarm with the trumpets; and ye shall be remembered before the LORD your God, and ye shall be saved from your enemies.

10 Also 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.

11 And 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.

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

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

14 In 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.

15 And over the host of the tribe of the children of Issachar [was] Nethaneel the son of Zuar.
