It's often because the Rabbis, in their infinite wisdom, saw connections we might miss. Take the story of Moses at the burning bush in Exodus, chapter 4. God gives him three signs to convince the Israelites that he's been sent to redeem them. But are these signs just miracles, or is there something deeper going on?

The first sign is the most striking: Moses puts his hand in his bosom, and when he takes it out, it's leprous, "like snow" (Exodus 4:6). A chilling image, right? But why this particular affliction?

The Shemot Rabbah, a compilation of rabbinic interpretations on the Book of Exodus, offers a fascinating explanation. God tells Moses, "It is just like the serpent who, when he engaged in slander, I afflicted him with leprosy." Remember the serpent in the Garden of Eden? According to the Midrash, the serpent's punishment, "Cursed [arur] are you from all the animals" (Genesis 3:14), included leprous spots. Rabbi Elazar says that those spots on the serpent are leprous marks. Slander, it seems, is a particularly virulent poison.

But why the bosom? The Midrash continues: "It is because slander is typically told in secret." Think about it – gossip, lashon hara (evil tongue), thrives in hushed tones, behind closed doors. As it says in Psalms 101:5, "He who slanders his neighbor in secret, I will destroy [atzmit]." The Midrash connects atzmit to leprosy, citing Leviticus 25:23: “In perpetuity [litzmitut],” which is translated as completely [laḥalutin]. The passage then references Megillah 8b to show that muḥlat, derived from the same root as laḥalutin, is used in the context of leprosy.

So, Moses's leprosy is a direct consequence of his initial reluctance to accept God's mission. According to Rabbi Yehoshua of Sikhnin, said in the name of Rabbi Levi: From here you learn that anyone who suspects another of something which is untrue of him, is afflicted in his body.

But there's more! God then tells Moses to put his hand back in his bosom, and when he removes it, it's healed (Exodus 4:7). How does this relate to the Israelites? The Midrash offers a powerful analogy: "Just as a leper causes impurity, so do the Egyptians render you impure. And just as he [the leper] is purified, so is the Holy One blessed be He destined to purify Israel."

The leprosy and its healing become a metaphor for the Israelites' experience in Egypt – a period of spiritual impurity and suffering, followed by eventual redemption and purification.

Our Rabbis say that the punishment was delayed until Moses' hand was outside of his bosom, so as to not cast aspersions on Moses’s flesh. However, regarding the healing, it was healed in his bosom. Alternatively, from here punishments are delayed before being exacted upon the righteous, while the [divine] attribute of goodness takes effect quickly.

Finally, there's the third sign: turning water into blood (Exodus 4:9). The Shemot Rabbah connects this to Moses's later sin of striking the rock to bring forth water (Numbers 20:10). The Midrash sees a link between the word vayazuvu ("flowed out") in Psalms 78:20 and the blood flow described in Leviticus 15:25. The Midrash suggests that Moses was punished through the water turning into blood, a consequence of his lack of faith.

Interestingly, while the leprosy and the snake were reversed, the blood was not. The first two signs were restored to their original state, but the sign of the blood was not restored to its original state because He did not wish to forgive Moses for the sin of the water.

What does this all mean for us today? Perhaps it's a reminder of the power of our words, the importance of faith, and the cyclical nature of suffering and redemption. Just as Moses's hand was healed, and just as the Israelites were eventually freed from Egypt, we too can find healing and redemption, even in the darkest of times.

These ancient texts invite us to see beyond the surface of the biblical narrative and to uncover the hidden layers of meaning that resonate across generations. It reminds us that even seemingly simple stories can hold profound lessons about human nature, divine justice, and the enduring hope for a better future.
