Three elements are to be discerned in this brachah. It begins with Teka b’shofar which shall proclaim to the nations, commanding them to set free the Jewish people and allow them to liberate their Land. Following this, a banner will be raised for all that long for redemption. This is now possible because the nations have been given the “message” via the blast of the great shofar. The opportunity for return is now available for all who seek it. Last, the opportunity is available for all of the lost Jews who have strayed due to ignorance, who, through no fault of their own, never had the chance to be a part of the glorious Jewish nation. They will be gathered in together with the rest of the Jewish nation. This does not apply to those who fully and knowingly strayed away from their people. They are not lost. They have abandoned their brothers and sisters.
