Aaron: "What! Great enough is our sorrow through those who have been in Egypt from the beginning, and thou takest more to the land?"
Moses recognized that Aaron was right, and he sent his wife and his sons back to his father-in-law Jethro.
He was no less magnanimous than Aaron. If the elder brother felt no envy on account of the younger brother's dignity, the younger brother did not withhold from the other the teachings and revelations he had received. Immediately after meeting with Aaron, Moses told him all that God had taught him, even the awful secret of the Ineffable Name communicated to him on Mount Horeb.
