Even though the blowing of the shofar on Rosh Hashanah is a Biblical decree, it hints at something, i.e., “Wake up, sleepers, from your sleep! And slumberers, arise from your slumber! Search your ways and return in teshuvah and remember your Creator! Those who forget the Truth amidst the futility of the moment and are infatuated all their years with vanity and nothingness that will not help and will not save, examine your souls and improve your ways and your motivations! Let each of you abandon your wicked ways, and your thoughts which are no good.” (Maimonides Mishneh Torah, Hilchot teshuvah 3:4)
The shofar is a peculiarly powerful instrument. Its call pierces the air – we cannot ignore its sound. It has been used to summon people for battle, as a warning, as a blast to terrify the enemy. It was heard at Sinai – though it is not clear who was blowing it. The ram caught in a thicket at the binding of Isaac was caught by its horn, from which comes the rabbinic idea that God instructed Abraham that his descendants should blow the shofar whenever they were in danger of divine punishment – the merits of the protagonists in the Akedah would be brought in front of God who would therefore forgive us. Bible tells us to blow it to announce the New Moon of Tishri, and from that comes the idea that every new month is publicised in this way.
The sound of the shofar is also close to the sounds of wailing and of more gentle but insistent crying. The Talmud (Rosh Hashanah 33b) discussing the sounds has one tanna saying the Teruah means a wailing sound, the Sh’varim denotes moaning or broken sighs. The Tekiah, the straight blast of sound, is both introductory and closing sound, to contain and to announce the sorrowful nature of the other calls.
The shofar does much of our work for us. It is designed to wake us up, but also to give voice to our fears and anxieties, and then to strengthen us in our battle to become our best selves. There is a debate in the Talmud about whether the shofar should be bent or straight, and the implication is that the shofar represents the person who is approaching God – should we approach with our backs straight and, so to speak, look God in the eye while asking for forgiveness, or should we be bent with the weight of our sorrow at the sin we are carrying, and looking down to the ground?
There is no answer given – all shofarot whether straight or curved are permissible. Each of us, however we feel about ourselves, can come before God and under that divine gaze, be open about what and who we currently are.
