Kabbalah zu Dewarim 6:22

Come and behold, had Sarah not been taken to Pharaoh, he would not have been plagued. And the result of Pharaoh's plague was another plague, so the Egyptians suffered great plagues (as Israel left Egypt). It is written, "great plagues," in this passage, and, (when Israel left Egypt), it is written, "And Hashem showed signs and wonders, great and sore, upon Egypt" (Devarim 6:22). Because there were ten plagues, (Pharaoh also suffered) ten plagues here. And just as the Holy One, blessed be He, performed miracles and showed His great might during the night, so here as well, the Holy One, blessed be He, performed miracles and mighty deeds at night.
