“Craft for you” – from your own. “Craft for you” – for yourself you craft, but not for another. You use them, but another does not use them. Know that Joshua, Moses’s disciple, did not use them, but rather shofars.
When he came to wage war in Jericho, seven nations assembled in Jericho, as it is stated: “You crossed the Jordan, and you came to Jericho; the masters of Jericho made war against you, the Emorites, the Perizites, the Canaanites, the Hitites, the Girgashites, the Hivites, and the Yevusites, and I delivered them into your hand” (Joshua 24:11). Were the masters of Jericho seven nations? Rabbi Shmuel bar Naḥmani said: Jericho was the safeguard of the Land of Israel.
If Jericho is conquered, immediately the rest of the Land will be conquered. That is why the seven nations assembled in it. What is written there? “The people shouted, and they sounded the shofars” (Joshua 6:20) – it teaches that even his disciple Joshua did not use them.
Do not say only for Joshua, but even Moses, as they were sequestered while he was still alive. Rabbi Yitzḥak said: Moses says, when he comes to take his leave of the world: “Assemble to me all the elders of your tribes, and your foremen” (Deuteronomy 31:28). Where were the trumpets to sound and assemble them? It is, rather, that they were sequestered while he was still alive.
Rabbi Yehoshua of Sikhnin in the name of Rabbi Levi said: It is to realize what is stated: “There is no dominion on the day of death” (Ecclesiastes 8:8). That is, “craft for you two silver trumpets” – craft them for you, and no one else will use them all the days of your life.
