Verses 3-10:
God gave precise instructions for this ceremony which was to become a perpetual ordinance in Israel. Each provision had symbolic meaning, which related to God’s plan of redemption.
"Lamb" seh, may refer to either a young sheep or a goat. In this case, it must be of the "first year."
"According to the house of their fathers," lit., "for a father’s house," or a family.
"Too little for a lamb," or "too few to eat the meal at a sitting." In this instance, the meal should be shared with a neighbor. The meal must be prepared with consideration for the number likely to eat. Sharing the Pascal meal illustrates the obligation of Christians to share with others the Gospel of Christ, Ac 1:8; Mt 5:15, 16.
"Without blemish," the lamb must not be lame, sick, marred in any way. The Law later expressly forbade any blemished animals for sacrifice, see Le 22:20-25. This provision typifies the Lamb of God, who is "holy, harmless, undefiled, separate from sinners" (Heb 7:26), and who is the "lamb without blemish and without spot" (1Pe 1:19).
The lamb was to be penned up from the tenth day to the fourteenth, likely to give time to observe it carefully to determine that it had no blemish.
The "whole assembly," all Israel, was to partake of this rite.
The lamb was to be slain, its blood caught in a basin (v. 22), and then sprinkled on the "upper door post" (lintel) and the two side posts or door frames. Fig. A shows the significance of this provision. Lines drawn from where the blood was sprinkled form a cross. [figure in hardbound commentary]. This pictures the cross upon which the Lamb of God died for man’s redemption from sin.
The Hebrews commonly boiled the meat of sacrificial meals, 2Sa 2:14, 15. The Paschal meal was to be roasted, which was simpler and quicker than boiling. Since haste was essential, this was the best way to prepare the meat.
The Paschal meal was to be eaten with "bitter herbs" or vegetables, a picture of the bitterness of Israel’s servitude in Egypt.’ Jewish tradition says that chicory, endive, wild lettuce, and nettles were included in this.
The Paschal lamb was to be eaten in its entirety. This symbolizes the total Person of Christ our Passover, who was offered for sin, Isa 53:1-5. It also illustrates the unity of God’s people.
"Purtenances"quereb, denotes the intestines. Jewish tradition says the intestines were removed, washed and cleansed, then replaced to be roasted and eaten.
The Lamb was to be totally consumed the night of the Paschal feast. Nothing was to be left until the morning. This symbolizes the total Person of Christ who is the one Offering for sin.
