We learn that in, "Even the gold of the wave offering," 'wave' always means lifting upward, not drawing downward, and that this term applies to gold and brass but not silver. Silver is Chassidim and it can be drawn downward, but whenever gold descends its beauty and light are dimmed. Gold needs to be raised but silver needs to be spread downward, as in "And the silver of them that were numbered of the congregation."
Rabbi Shimon turns to: "For Hashem Elohim is a sun and shield...," saying that the sun is the secret of Yud Hei Vav Hei and the shield is the secret of the Holy Name Elohim. Together 'a sun and shield' are the union of Zeir Anpin and Malchut. A similar meaning is deduced from "Hashem will give grace and honor."
We are told that God conceals the primordial light from the wicked but never withholds it from those 'who walk upright.' Therefore the first light does not move upward; it spreads downward and is revealed to them. Rabbi Shimon says when the priest spreads his hands in blessing the Shechinah comes to him and fills his hands. Then the priest raises his right hand above his left and everything is blessed by the source of all, the World to Come. The candles are lit and all blessings are drawn from above.
