While in bondage in Mitzraim, the B’nei Yisrael had sunk to the 49th level of impurity, having neglected to distance themselves from the surrounding environment of idolatry. The Midrash records that when about to cross through the Sea of Reeds, the angels questioned their merit, saying both these and those, i.e., the Children of Israel and the Egyptians, were both idol worshippers. Why should these be spared, and the others not? Yet, H’Shem honored the covenant that he made with Abraham, Isaac, and Jacob, in order to bring His newly acquired nation out of bondage, and into covenant relationship with Him through the Torah.
H’Shem brought us out of Egypt to Mount Sinai, where He gave us the Torah. He had said to Moses, “This shall be the token unto thee, that I have sent thee: when thou hast brought forth the people out of Egypt, ye shall serve G-d upon this mountain” (Exodus 3:12, JPS 1917 Tanach). The revelation of Mount Sinai was the pinnacle of the redemption. “The tablets were the work of G-d, and the writing was the writing of G-d, graven upon the tablets” (Exodus 32:16, JPS). The Hebrew word for engrave is charut. The Sages note that the word cherut, meaning “freedom” is from the same shoresh (root word). This implies that our true freedom is derived through Torah.
B’nei Yisrael, in a manner of speaking, was also enslaved to sin in Egypt, having assimilated to the immorality of Egypt at that time. Although freed from actual physical bondage, they were still slaves to sin; yet, through the Torah, we may seek freedom from bondage to the yetzer harah (the evil inclination). We may break through the limitations of our own personal Mitzraim (Egypt; from “nitzavim,” limitations), and, figuratively speaking, pass through the Yam Suf (Dividing of the Sea), into the freedom that entails a responsibility to follow our yetzer tov (good inclination).
