With a mighty hand: the cattle plague…With an outstretched arm: the sword…with great terror: the revelation of the divine presence…with signs: the rod…with wonders the blood: The commentators struggled to understand why only two plagues were singled out from all the wonders that took place in Egypt. The first fruit passage is an expression of gratitude; it is expressed not by mentioning the bad things that happened to others but by mentioning those places where God singled out Israel from Egypt. This only took place in those cases where the Egyptians and the Israelites were together in the same place and God singled out the Egyptians for punishment and spared the Israelites. One place where the Torah explicitly tells us that this happened is the cattle plague. The Torah states, “The Lord will make a distinction between the livestock of the Israelites and the livestock of the Egyptians so that nothing shall die of all that belongs to the Israelites.” (Exodus 9:4) Even though the livestock of the Egyptians and the Israelites were in the same place, the livestock of the Egyptians died but not that of the Israelites. The same is true in the case of the tenth plague: God singled out the homes of the Israelites from those of the Egyptians. In all the other cases the Torah is not explicit in saying that the Israelites and the Egyptians were in close proximity.
Having mentioned these plagues, the Haggadah now speaks about the other ways in which God showed the Israelites favor: He did so by revealing His presence, through the wonder of Moses' rod, and through "the blood." Each of these was a wonder that God told Moses to show the Israelites so that they would be convinced of God‟s power. By turning his staff into a snake, making his arm become leprous and then turning some water from the Nile into blood in the presence of the Israelites, they would become convinced of God‟s power. In the end Moses did not perform the wonder of the leprous arm since this was meant to be a warning to Moses not to slander against the people of Israel. The reference to blood is not a reference to the plague of blood but the suggestion by God to turn some water into blood for the people of Israel.

But know that the Lord hath set apart (הפלה): – He hath set aside and separated. So also, “the Lord shall set apart (והפ֫לה) between the cattle of Israel” (Exod. 9:4). And its interpretation: He has separated me from all Israel to be king; on the analogy of “The Lord separated the tribe of Levi” (Deut. 10:8). And why? Because He knows me to be

ונפלינו אני ועמך SO SHALL WE BE DISTINGUISHED, I AND THY PEOPLE — through this very thing we shall become different from all the peoples. נפלינו is of the same root and meaning as in (Exodus 9:4) “And the Lord shall make a separation (והפלה) between the cattle of Israel etc.”

והפליתי means I WILL SEPARATE. Similar is, (Exodus 9:4) “And the Lord will make a separation (והפלה)”; so, also, (Deuteronomy 30:11) “It is not נפלאת from thee״ — that is, “it is not separated and set at a far distance from thee”.
