Page "Aaron" Paragraph 13

At the command of Moses he stretched out his rod in order to bring on the first of three plagues ( Exodus 7: 19, 8: 1, 12 ).

In the infliction of the remaining plagues, he appears to have acted merely as the attendant of Moses, whose outstretched rod drew the divine wrath upon the Pharaoh and his subjects ( Exodus 9: 23, 10: 13, 22 ).

The display of potency from Aaron's rod had already been demonstrated in the presence of Pharaoh's magicians ; when Aaron's rod was thrown down to the ground it had turned into a snake, so Pharaoh's magicians performed the same act with their own rods.

However, Aaron's snake ate up all the other snakes ( Exodus 7: 9 ) proving his rod was victorious.
