1 And the LORD spake unto Moses, saying, 2 Make thee two trumpets of silver; of a whole piece shalt thou make them: that thou mayest use them for the calling of the assembly, and for the journeying of the camps. 3 And when they shall blow with them, all the assembly shall assemble themselves to thee at the door of the tabernacle of the congregation. 4 And if they blow but with one trumpet, then the princes, which are heads of the thousands of Israel, shall gather themselves unto thee. 5 When ye blow an alarm, then the camps that lie on the east parts shall go forward. 6 When ye blow an alarm the second time, then the camps that lie on the south side shall take their journey: they shall blow an alarm for their journeys. 7 But when the congregation is to be gathered together, ye shall blow, but ye shall not sound an alarm. 8 And the sons of Aaron, the priests, shall blow with the trumpets; and they shall be to you for an ordinance for ever throughout your generations. 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 out of 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. 16 And over the host of the tribe of the children of Zebulun was Eliab the son of Helon. 17 And the tabernacle was taken down; and the sons of Gershon and the sons of Merari set forward, bearing the tabernacle. 18 And the standard of the camp of Reuben set forward according to their armies: and over his host was Elizur the son of Shedeur. 19 And over the host of the tribe of the children of Simeon was Shelumiel the son of Zurishaddai. 20 And over the host of the tribe of the children of Gad was Eliasaph the son of Deuel. 21 And the Kohathites set forward, bearing the sanctuary: and the other did set up the tabernacle against they came. 22 And the standard of the camp of the children of Ephraim set forward according to their armies: and over his host was Elishama the son of Ammihud. 23 And over the host of the tribe of the children of Manasseh was Gamaliel the son of Pedahzur. 24 And over the host of the tribe of the children of Benjamin was Abidan the son of Gideoni. 25 And the standard of the camp of the children of Dan set forward, which was the rereward of all the camps throughout their hosts: and over his host was Ahiezer the son of Ammishaddai. 26 And over the host of the tribe of the children of Asher was Pagiel the son of Ocran. 27 And over the host of the tribe of the children of Naphtali was Ahira the son of Enan. 28 Thus were the journeyings of the children of Israel according to their armies, when they set forward. 29 And Moses said unto Hobab, the son of Raguel the Midianite, Moses' father in law, We are journeying unto the place of which the LORD said, I will give it you: come thou with us, and we will do thee good: for the LORD hath spoken good concerning Israel. 30 And he said unto him, I will not go; but I will depart to mine own land, and to my kindred. 31 And he said, Leave us not, I pray thee; forasmuch as thou knowest how we are to encamp in the wilderness, and thou mayest be to us instead of eyes. 32 And it shall be, if thou go with us, yea, it shall be, that what goodness the LORD shall do unto us, the same will we do unto thee. 33 And they departed from the mount of the LORD three days' journey: and the ark of the covenant of the LORD went before them in the three days' journey, to search out a resting place for them. 34 And the cloud of the LORD was upon them by day, when they went out of the camp. 35 And it came to pass, when the ark set forward, that Moses said, Rise up, LORD, and let thine enemies be scattered; and let them that hate thee flee before thee. 36 And when it rested, he said, Return, O LORD, unto the many thousands of Israel.

“Make for yourself two trumpets of hammered silver.” The army is led by two trumpets because the people are called to readiness in faith by the two commandments of charity. Scripture bids them to be made of silver, so that the words of the preachers may shine with gleaming light and not confuse the minds of the hearers with any darkness of their own. They are to be hammered, because those who preach the life to come grow through the blows of the present tribulations. Scripture says well, “When the short signal sounds, the camps will move.” When the preacher’s word is subtle and concise, the hearers are aroused more ardently for the struggle against temptation.

We can better persuade proud men to do what is useful if we say that their setting out will profit us rather than them, or if we say that improvement will profit us rather than them and ask that the cost be on our account, not theirs. For pride is easily turned to good if it can be adapted to the profit of others. Thus Moses, with God guiding him, advanced through the desert with a column of cloud going before him. When he wished to draw his relative Hobab away from his life with the Gentiles and subject him to the lordship of almighty God, he said, “We are going to the place that the Lord will give us. Come with us, so that we can do you good, for the Lord has promised good to Israel.” When Hobab answered, “I will not go with you but will return to my land, where I was born,” Moses added, “Do not leave us. You know where we should make camp in the desert, and you will be our guide.” Moses’ mind was not limited by ignorance of the route. For knowledge of the Deity had made him familiar with prophecy. The column had gone before him. Familiar speech had taught him about all things interiorly, through careful conversation with God. But this prudent man, speaking to a proud listener, asked Hobab to give him help. Moses needed Hobab as a guide along the way, so that he could be Hobab’s guide in life. So Moses acted so that the proud listener, as he urged the better way on him, would become more devoted to him if he were thought to be indispensable. He thought he outranked Moses, who asked him for help, and thus yielded to Moses’ words as Moses entreated him. Exposition of the Old and New Testament, Numbers
