Yalkut Shimoni on Torah 206:6

Another interpretation: "I place My wrath (evrah) and My terror upon Egypt" - evrah means nothing other than fury, and so on. "And He will see the blood" - is not everything revealed before Him? And so on. "And the LORD will pass over the door" (Exodus 12:23). And these matters are an argument from minor to major: if the blood of the Passover in Egypt, which is the lighter case - for it lasted only for the moment, and does not apply by day and by night, and does not apply for the generations - yet of it is written, "He will not allow the Destroyer to enter," then the mezuzah, which is the weightier case - for it contains the special divine Name ten times, and applies by day and by night, and applies for all generations - how much more so that He will not allow the Destroyer to enter. And what brought it about (that protection should ever fail)? Our iniquities, as it says, "Your iniquities have turned these away" (Jeremiah 5:25). And it says, "But your iniquities have separated" (Isaiah 59:2). "And you shall keep this matter" (Exodus 12:24) - to bring the Passover of the generations, that one shall bring it only from the lambs and from the goats. It is written, "as a statute for you and for your children forever." Why is this said? Because it says, "and they shall take of the blood," I might hear that even the women are included; therefore Scripture teaches, "as a statute for you and for your children" - the men, but not the women.
