Do not eat any of the meat raw or cooked in boiling water, but only roasted over the fire—its head and legs and inner parts.
Moses and Aaron here receive of the Lord what they were afterwards to deliver to the people concerning the ordinance of the passover, to which is prefixed an order for a new style to be observed in their months (Exo 12:1, Exo 12:2): This shall be to you the beginning of months.
Commenting on Exodus 12:1-20
Eat not of it raw,.... Not roasted enough; and so Jarchi says, that what is not sufficiently roasted, or is not thoroughly and down roasted, is in the Arabic language called (u), the word here used; and so Maimonides (w) says it signifies flesh, on which the fire begins to operate, and is roasted a little, but not enough for eating.
Eat not of it raw--that is, with any blood remaining; a caveat against conformity to idolatrous practices. It was to be roasted whole, not a bone to be broken, and this pointed to Christ (Joh 19:36).
