The book of Vayikra – Leviticus opens with: God called to Moshe and spoke to him from the Tent of Meeting…The Rabbis say this verse teaches that God is, as it were, well-mannered.  He did not abruptly begin a conversation with Moshe but first he called him and only then did he begin to speak to him. Vayikra is the middle book of the Torah, it is replete with the particularities and unique laws and customs of the Jewish people. Before any of this begins, we first learn how to be a mensch and only then do we graduate to the particular laws and customs of our people.
