Another interpretation, “draw, and take for yourselves lambs” – that is what is written: “All who serve graven images shall be shamed” (Psalms 97:7). When the Holy One blessed be He said to Moses to slaughter the paschal offering, Moses said to Him: ‘Master of the universe, how can I do so? Do You not know that lambs are the gods of Egypt?’ As it is stated: “Behold, were we to sacrifice the abomination of the Egyptians before their eyes, would they not stone us?” (Exodus 8:22).
The Holy One blessed be He said to him: ‘By your life, Israel will not depart from here until they slaughter the god of Egypt before their eyes, as I will thereby inform them that their gods are nothing.’ And we find that He did so, as on that night He smote the firstborn of Egypt, on that night Israel slaughtered their paschal offerings and ate them, and the Egyptians saw their firstborn killed and their gods slaughtered and they were unable to do anything, as it is stated: “The Egyptians were burying they whom the Lord had smitten among them, all their firstborn, and upon their gods the Lord administered punishments” (Numbers 33:4); that is: “All who serve graven images shall be shamed.”
