Then, "when I see the--_blood_--on the--_lintel_--and on the two--_side-posts_--I will not go in and--_kill the first-born_!" Yes. That was what God said. I have sometimes thought I could see an Egyptian soldier that night with his armor on, going up to one of the Israelites and asking, "What is that you are putting on the door?" "It is some lamb's blood." "What are you putting it on for?" "Because my God has told me to." Then with a strut he has turned on his heel and walked away, muttering to himself, "What a big fool that Jew is!" But see! the hands on the clock begin to get around. It is now pointing to--_midnight_. Yes, pretty soon it strikes one--two--three, up to--_twelve_. And then! Oh! the angel of death went from one house to another, and in every one that didn't have--_the blood_--on it, the first-born was--_killed_. Yes! And one wail of woe went up from Egypt that night. Fathers and mothers, from Pharaoh in his beautiful palace, to his poorest servant, were weeping and wailing and lamenting their first-born, slain by the hand of the angel of God. But some houses escaped. The ones with the--_blood_ on. Had there been any death in those houses? _No, sir._ Think. What had died? _A little lamb._ Yes; a little lamb had been killed and his blood put in--_a basin_. And then--suppose the basin had been set behind the door, would that have done? _No, sir._ The blood must be sprinkled on the--_door_, and it most be sprinkled by a bunch of--_hyssop_. Yes; it must all be done exactly as God had said. Then the door that had the blood upon it was passed over by the angel, was it? _Yes, sir._ And what was done to the house where there was no blood? What did the angel do? _Went in._ Yes, and--_slew the first-born_. [Mr. Wells then called a little boy up to the board, drew a rough sketch of three or four door-frames, on two of which he used the red chalk, making marks to represent blood. The boy was then asked, with the class, to point out which houses the angel would enter, and which pass over, thus drilling the fact impressively and perfectly into the scholars' minds, as also the reason for the angel's choice--the _blood_ of the lamb.]
