Moses learned from Gd. Moses then taught it to Aharon, and Aharon sat by his side. Moses then taught it to Aharon's two sons, who then sat by their side. Moses then taught it to the elders. Moses then left, and Aharon taught it to the others. Aharon left, and his sons taught it to the others. The sons left, and the elders taught it to each other. This way, each learned four times.
