Could the Egyptians save their animals from the plague of Dever, by bringing them into their homes (as Moshe later encouraged them to do before the plague of Barad)?
If, in fact, the animals inside the Egyptians' houses would be spared from Dever, why didn't Moshe warn them explicitly to bring in their animals?
Why does the Torah specify, regarding this plague, that there would be a distinction between the flocks of Yisrael and those of the Egyptians?
What was unique about the plague of Dever? What was it supposed to teach Pharaoh?
1. Mafteach to Shemos 9:4:1:6, also see 2. Mafteach to Shemos 7:14:8:1 regarding the Makos' categorization as De'tzach A'dash Be'achav.
If all the Egyptians' animals died in this plague of Dever, what animals were later affected by the plagues of Shechin and Barad (Shemos 9:10, 9:25)? Which firstborn animals died during Makas Bechoros (12:29); and how did the Egyptians obtain horses to pursue the Bnei Yisrael to the Yam Suf (14:9)?
Why, specifically in this plague, did Pharaoh investigate whether the Bnei Yisrael had suffered the effects of the Makos? What did he find?
