Matters being thus prepared, the service began. And let not the Reader overlook the employment of the priests, who it is said were busied in offering burnt-offerings and the fat until night. The sufferings of Jesus opened at the evening if we take in the garden scene, which as it formed so interesting a part undoubtedly we must. And the priests were alone engaged in this service preparatory to the great day. The sprinkling of the blood after killing the lamb, were certainly striking circumstances appointed by the Holy Ghost to lead by faith to the Saviour. Indeed everything in it was typical of the Lord Jesus. A lamb of the first year, without blemish and without spot; the setting it apart four days before; the slaying it and roasting it whole; and not a bone of it to be broken; all these were very highly significant of Jesus. And as the paschal lamb was to be eaten, and wholly eaten, nothing of it being to be left, what could more decidedly speak in reference to Jesus, who as Christ our passover is not to be looked upon only, but by faith fed upon, and lived upon, and wholly so; all Christ, and all in Christ, to form a complete Saviour: surely such views held forth to the church, both at the original institution of it after coming out of Egypt, and now again in the days of Josiah so fully revived, at a period distant from the deliverance out of Egypt of at least 850 years; nothing can more fully display the vast importance of the thing itself, and of the sense in which the Holy Ghost was pleased the church should consider it with reference to the body of Jesus Christ in his offering upon the cross for human sin once for all.
2 Chronicles 35:11-17
11 And they killed the passover, and the priests sprinkled the blood from their hands, and the Levites flayed them.
12 And they removed the burnt offerings, that they might give according to the divisions of the families of the people, to offer unto the LORD, as it is written in the book of Moses. And so did they with the oxen.
13 And they roasted the passover with fire according to the ordinance: but the other holy offerings sod they in pots, and in caldrons, and in pans, and divided them speedilyd among all the people.
14 And afterward they made ready for themselves, and for the priests: because the priests the sons of Aaron were busied in offering of burnt offerings and the fat until night; therefore the Levites prepared for themselves, and for the priests the sons of Aaron.
15 And the singers the sons of Asaph were in their place,e according to the commandment of David, and Asaph, and Heman, and Jeduthun the king's seer; and the porters waited at every gate; they might not depart from their service; for their brethren the Levites prepared for them.
16 So all the service of the LORD was prepared the same day, to keep the passover, and to offer burnt offerings upon the altar of the LORD, according to the commandment of king Josiah.
17 And the children of Israel that were presentf kept the passover at that time, and the feast of unleavened bread seven days.
