1 A scoundrel named Sheba son of Bichri, a Benjaminite, happened to be there. He sounded the shofar and proclaimed: “We have no portion in David, No share in Yishai‘s son! Every man to his tent, O Yisrael!”

20:1 He sounded the horn
The ram’s horn, shofar (שופר), has a critical place in Judaism. Hashem commands the Jewish people to listen to the sounds of the shofar on Rosh Hashana, and there are times that it is to be blown in the Beit Hamikdash, such as on public fasts. It is also to be sounded at the end of the yovel, the Jubilee year. But in addition to these spiritual functions, it also has military usages. The shofar serves as the method of assembling soldiers and of sounding a warning call. The common feature is that in all these cases, the shofar is sounded to get everyone’s attention to fulfill their particular mission. It serves to awaken those who are slumbering, either physically or spiritually.
