And the Lord spoke to Moses, saying: “Make two silver trumpets for yourself; you shall make them of hammered work; you shall use them for calling the congregation and for directing the movement of the camps." (vv.1-2)
The two silver trumpets were used to, direct the movement of the camps for marching and for battle, and also to gather the nation together for an assembly. These instruments were about two feet long with very narrow tubes with a flared opening at the end. When blown in certain patterns, they emitted a bright and piercing sound that would both get the attention of the people, and communicate clearly to them the desired intent.
The trumpets were helpful tools for the journey to the Promised Land. Without them it would be difficult to assemble the nation and march towards Canaan. Distinctive sounds were made to indicate; gathering for assembly, marching, or warfare. Therefore, when Israel heard the trumpets, they would gathered as directed.
Before we can obey God, we must first give Him our attention, and we can not do that if we are not listening. While God does not use trumpets to get our attention today, He still guides and directs our lives (if we will let Him) through His Spirit, that still small voice through His Word. Then, like the children of Israel, we must move forward and obey His direction.
The Truth: "God, who in various times and in various ways spoke in times past to the fathers by the prophets, has in these last days spoken to us by His Son, whom He has appointed heir of all things, through whom also He made the worlds." (hebrews 1:1-2)
