Kabbalah Yunus 2:2: Tikkunei Zohar

similarly "Ad-nai appointed a great fish to swallow Jonah" to kill him. It is not written "to swallow Jonah" but "to swallow ET Jonah" and the particle ET is there to include the Faithful Shepherd [Moshe] who would bring Torah in his hands, which is from ALEF to TAV, and all reincarnations were in his hands, and this is the great fish, about which it is written "the great serpent" (Ezekiel 29:3), which is the fish of Egypt and its partner is Dagah (Jonah 2:2) and "the bowels of the Dagah" are Egypt.
