90. "But lift up your rod" (Shemot 14:16). Lift up your rod, upon which is etched the Holy Name, and stretch your hand to the side of the Holy Name. As soon as the waters see the Holy Name, they will flee from it. Therefore, stretch your hand to one side OF THE ROD, because the other sides of the rod will be necessary for other matters, NAMELY, TO HIT THE ROCK.
91. Rabbi Elazar said, I see that sometimes this rod is called 'the rod of Elohim' and sometimes it is called 'the rod of Moses.' Rabbi Shimon said, In the book of Rabbi Hamnuna Saba (the elder), he says that it is all one, whether it says 'THE ROD of the Holy One, blessed be He,' or 'THE ROD of Moses.' The purpose of this rod is to rekindle the aspect of Gvurah. Therefore, THE VERSE SAYS, "Stretch out your hand," WHICH MEANS the left hand, which is at the side of Gvurah.
92. Rabbi Shimon said, Woe to those who do not see and do not look at the Torah. The Torah calls before them daily but they do not pay attention. Come and behold, water rises in the world and water emerges from the side of Gvurah. But now the Holy One, blessed be He, wanted to dry up the water. Thus, why DOES THE VERSE SAY, "And stretch out your hand," which is the left hand, NAMELY GVURAH?
93. HE ANSWERS, Rather, "lift up your rod," is to dry up the water, and "stretch out your hand," is to return the water, to activate the side of Gvurah and to turn the water on Egypt. Therefore, there are two things here, for it is written, "Lift up your rod, and stretch out your hand over the sea, and divide it." ONE ELEMENT IS TO DRY OUT THE WATER, AND THE OTHER IS TO RETURN THE WATER OVER EGYPT.
94. HE ASKS, HOW WAS IT POSSIBLE TO DRY THE LAND IN THE MIDST OF THE SEA, for there were pits IN IT? HE ANSWERS, THE Holy One, blessed be He, performed a miracle within a miracle, as it is written, "And the depths were congealed in the heart of the sea" (Shemot 15:8). They were walking on the dry ground within the sea. This is what is written, "And the children of Yisrael went into the midst of the sea on the dry ground" (Shemot 14:22).
