The ten plagues - De-Tza-Kh A-Da-Sh Be-A-Cha-V (116b)

The Gemara in Pesachim 116b presents the mnemonic for the plagues, an essential tool for remembering their order. Rabbi Yehudah gave us a gift: an acronym that allows us to navigate the Haggadah text with clarity. This is not just a memory aid; it's a starting point for deeper understanding.

1. 1Break down the mnemonic into three groups of three plagues (the last one stands alone).
2. 2Memorize the plagues within each group.
3. 3Repeat the mnemonic aloud until it's firmly embedded in your memory.

The mnemonic is not just a list. It reveals a deeper structure. Sages, primarily Rashi, saw in each triad of plagues a unique theological purpose. This is not a coincidence, but a deliberate divine plan, designed to reveal Hashem to the world – and to Pharaoh in particular.

The first triad ('De-Tza-Kh') aimed to prove Hashem's existence and His role as Creator. The second triad ('A-Da-Sh') demonstrated His specific providence in the world, and His ability to distinguish between Israel and Egypt. The third triad ('Be-A-Cha-V') emphasized Hashem's absolute power as the sole ruler over nature and humanity.

The Haggadah continues and deepens with Rabbi Yose ha-Gelili, who is not satisfied with a simple count. He multiplies the plagues, teaching us that each plague in Egypt was actually a series of events, and that the plague at the Sea was many times more severe.

The explanation is that each plague in Egypt was equivalent to five plagues, and at the Sea, each plague was equivalent to fifty. He learns this from various verses that hint at the intensity of the plagues and the divine response. This enhances the sense of wonder and majesty of the redemption.

Rabbi Yose ha-Gelili's exaggerated count serves a dual purpose: to amplify the miracles performed in Egypt and at the Sea, and to emphasize the vast difference between the plague at the Sea and the plagues in Egypt. This is a lesson in humility and gratitude towards Hashem for the magnitude of the redemption.
