Kabbalah do Wyjścia 11:78

The verse, "flocks, and menservants, and women servants," refers to lower crowns of the Kelipot, which the Holy One, blessed be He, slew in Egypt. They are called "the firstborn of cattle" (Shemot 12:29), "the firstborn of the captive" (Ibid.), and "the firstborn of the maidservant" (Shemot 11:5). Esau took fright and came toward him; he feared Jacob as much as Jacob feared him.

This verse, in another place, in this way. He opened the discussion by saying, "And he slew an Egyptian man, a man of great stature, five cubits high" (I Chron 11:23), and all are related to the same secret. This Egyptian is that one who is known, "very great in the land of Egypt in the eyes of the servants" (Ex. 11:3), as he is great and honored. This is how the old man described him.
