Va'era 5775

We all know the acronym for the 10 plagues of Detzach, Adash, Be'achav (groups of 3, 3, and 4). Why is the grouping as such? The Kli Yakar explains that each group disproved Pharaoh's claims against Hashem. The first 3 plagues were to show that there is a G-d above everything: Hashem turned the Nile, their god, into blood. He then brought frogs from that very river who sanctified His name by leaping into furnaces. With lice, the magicians said "it is the finger of G-d." The next 3 plagues showed Hashem's Divine Providence over individuals by just attacking the Egyptians and their cattle. The last 4 plagues showed that there is only one G-d. Hashem blocked out the sun, which was considered a god, with locusts and darkness. The goat was also considered a god as well as the firstborn of all gods; Hashem killed the firstborns throughout Egypt with the last plague.
