Charles Spurgeon Commentary Exodus 12:8-9

"And they shall eat the flesh in that night, roast with fire, and unleavened bread; with bitter herbs they shall eat it. Eat not of it raw, nor boiled at all with water, but roast with fire; its head with its legs and with the inwards thereof." — Exodus 12:8-9 (ASV)

And they shall eat the flesh in that night, roast with fire, and unleavened bread; and with bitter herbs they shall eat it. Eat not of it raw, nor sodden at all with water, but roast with fire; his head with his legs, and with the purtenance thereof.

We are to have a whole Christ, with his head of wisdom and his heart of love, the walk and conduct of Christ, and all the inward secret life and grace of Christ, all to be ours.
