142. From the time of Adam, Jacob was destined to take from the serpent all these blessings, and the serpent was to remain accursed, NEVER to be released from them. And David, inspired by the Holy Spirit, asked, "What shall be given to you? Or what shall be done to you, you false tongue? Sharp arrows of the mighty" (Tehilim 120:3-4). What causes this evil serpent to bring curses upon the world, when he is, as they said, a serpent that bites and kills, but draws no pleasure from it?
143. "...False tongue." For the serpent deceived Adam and his wife and brought evil on him and the world. Then came Jacob, who took the blessings that were his own. "Sharp arrows of the mighty" refers to Esau, who harbored hatred toward Jacob on account of the blessings, as it is written, "and Esau hated Jacob because of the blessing" (Beresheet 27:41).
