Êxodo 6:14
There is no doubt that this is a mysterious passage. The Scripture wishes to demonstrate the origin of Moses, because his action now required it. His descent began from the firstborn of Jacob, that is, Reuben, and then to Simeon, and then to Levi. It went no further, because Moses was descended from Levi. These men who are mentioned here had already been mentioned among the seventy-five men in whom Israel entered Egypt. For God did not want the first or the second tribe, but the third—that is, the tribe of Levi—to be the priestly tribe. — QUESTIONS ON EXODUS 15
Êxodo 6:30
Moses says, "Behold, I have a weak voice, how will Pharaoh listen to me?" He appears to excuse himself for the weakness of his voice, not only due to the great number of the people but also due to the condition of one man. It would be remarkable if his voice were so weak that he could not be heard even by one man. Or perhaps the royal dignity did not allow them to speak at close range? For God says to Moses, "Behold, I gave you as a god to Pharaoh, and Aaron your brother will be your prophet." — QUESTIONS ON EXODUS 16
