Moses is considered the greatest prophet of the Jewish people. That’s strange, because according to Moses himself, he is “slow of speech and of a slow tongue” (Exodus 4:10). You would think that the greatest prophet of all time would at least be able to carry a sentence.
But Emor shows why Moses was so great: he gave the Hebrews their culture! This Torah portion has Moses teaching the Hebrews about Sukkot and Passover and Shabbat. Moses goes in depth about the Kohenim, the priestly class. Moses even goes into detail about the Jewish sense of justice.
It’s like a father giving his child a last name or a grandparent teaching a family recipe. It’s the reason why adopted kids learn about their biological parents, even though they already have parents that love them. Moses is the great prophet because he gave the Hebrews an identity.
