Beshalach: Chapter 9
"But lift up your rod"
Synopsis

Rabbi Elazar says that the rod, whether it is called 'the rod of Moses' or 'the rod of Elohim,' is for the purpose of rekindling the aspect of Gvurah. Rabbi Shimon clarifies that since water emerges from the side of Gvurah, "lift up your rod" is to dry up the water, and "stretch out your hand" is to return the water and spill it over the Egyptians.
