Last week we read about the construction of the Mishkan, God's house. This week we will read about the kohanim, the priests who served in God's house. To paraphrase Ibn Ezra: first they built the house and then the people came. Confident that God's instruction was good, we built His house according to His word, knowing that ultimately the people would come. When we are confident in God's word, in the sanctity of Shabbat and Kashrut, we do not need to violate them in the hope that people will come. For we know that as much as we keep the mitzvoth, the mitzvoth have kept us.
