출애굽기 12:24의 미드라쉬

What is written above? "And the Lord will pass over the opening." (Exodus 12:23) At that time - as if it were possible - He, Himself, stood at the opening. But rather, as it is the custom of the world - in the same way as when a butcher brings in his sheep and he takes red dye and marks each lamb and sheep that he wants to slaughter, in order to recognize which one to slaughter and which one not to slaughter; so too (Ibid.), "and he will see the blood" - as if it were possible - He stood at the entrance and pushed away the destroyer that he should not strike Israel. God said to them (Ibid. 24), "'And you shall keep this thing as a statute for you and your children forever" - in the same way as I did [this] for you today, so [too] will I do [it] for you in the future to come," as it is stated (Malachi 3:19), "As behold the day is coming, burning like a furnace, etc." "But [with] you, 'I will have pity upon you as a father has pity on his son.' (Ibid. 17)"
