We now come to the important subject, the use of the Sheep in sacrifice. No animal was used so frequently for this purpose as the Sheep, and in many passages of the Mosaic law are specified the precise age as well as the sex of the Sheep which was to be sacrificed in certain circumstances. Sometimes the Sheep was sacrificed as an offering of thanksgiving, sometimes as an expiation for sin, and sometimes as a redemption for some more valuable animal. The young male lamb was the usual sacrifice; and almost the only sacrifice for which a Sheep might not be offered was that of the two goats on the great Day of Atonement. [Illustration: A LAMB UPON THE ALTAR OF BURNT OFFERING.] To mention all the passages in which the Sheep is ordered for sacrifice would occupy too much of our space, and we will therefore restrict ourselves to the one central rite of the Jewish nation, the sacrifice of the Paschal lamb, the precursor of the Lamb of God, who taketh away the sins of the world. Without examining in full the various ceremonies of the Paschal sacrifice, we will glance over the salient points which distinguish it from any other sacrifice. The lamb must be a male, which is selected and examined with the minutest care, that it may be free from all blemish, and must be of the first year. It must be killed on the fourteenth of the month Abib as the sun is setting, and the blood must be sprinkled with hyssop. In the first or Egyptian Passover the blood was sprinkled on the lintels and doorposts of the houses, but afterwards on the altar. It must be roasted with fire, and not boiled, after the usual custom in the East; not a bone must be broken. It must be eaten by the household in haste, as if they were just starting on a journey, and if any of it should be left, it must be consumed in the fire, and not eaten on the following day.
