Exodus 12:9

OLBHeb;

Eat not of it raw, i.e. not thoroughly roasted, for such we also say is raw and so the Hebrew word na is understood by the Jewish and other doctors. It signified that Christ should suffer, as well as save, to the uttermost, all that was done for our sins. The purtenance; Heb. the inwards, which were to be taken and washed, and then to be roasted together with the rest. So do here except the fat, and caul, and kidneys which were reserved by God for himself, 2 Chronicles 35:12. But that exception was not made till after this time, and it seems not certain that that exception extended to the paschal lamb. These and the heads and legs are here mentioned, not to exclude other parts, but because they are not commonly roasted; but God would have the whole lamb roasted and eaten, to signify that we must have either nothing of Christ, or the whole Christ, and all his benefits, hist Spirit to sanctify and rule us, as well as his blood to save us.
