The formation of Israel’s cult takes place with God’s commands regarding the clothing of the priests and the High Priest and with the initiation of Aharon and his sons so that they can exercise the priestly functions. All this cleansing will make the altar “Holy of Holies” so that God can dwell among the Children of Israel. He announces that he will meet with the people at times determined by Him.

Tetzaveh 5784
Parashat Tetzaveh is the only one in the entire book of Exodus in which the name of Moshe does not appear. It is the portion in which a very detailed description is given of all the garments that the High Priest will have to wear. And who was the first High Priest, the first Cohen Gadol? Precisely Moshe’s brother, Aharon. It's as if Moshe or the Torah itself removes him from this part of the story to give Aharon a place. Inevitably, this sibling relationship brings to mind all the sibling relationships that have occurred so far in the Torah.
