Thus, the unity of the Jewish people is reflected on the three primary garments of the high priest: The names of the tribes that were engraved on the stones of the Breastplate, which rested on the high priest’s heart, signified the righteous among us.
The names of the tribes that were engraved on the stones affixed to the straps of the Ephod, which mainly covered the high priest’s back, signified formerly estranged Jews who have returned to full Jewish observance.
The bells and pomegranates of the Robe signified those Jews still struggling with their evil inclinations, yet are full of merits like seeds in a pomegranate. All of these Jews must be represented when the high priest enters the Sanctuary, for he must invoke the merit that is common to all his people.
Similarly, when we see people in need of a spiritual boost, we must first make them aware of their inherent worth: that they possess a soul that is truly a part of G-d. By welcoming them back into Jewish observance, we help them reconnect with their true selves. After this, we can help them shed whatever negativity remains in their lives and increase their performance of deeds of light and goodness.
