Blow When You Are Happy
Our parasha lists several uses for the chatzotrot (trumpets) that Bnei Yisrael were commanded to make. They were used in the desert, where all Bnei Yisrael were encamped together, for gathering the people or the leaders and as a sign to travel (Bamidbar 10:2-7). The Torah goes on to list purposes that were used throughout generations when the people were in their own land – to turn to Hashem when war or other trouble appeared (ibid. 9) and to blast joyous sounds on “your happy day (yom simchatchem), your moadim (special days within the year), and your new months … on your burnt offerings and your shelamim offerings” (ibid. 10).
