Exodus 12:8

They shall eat the flesh.

As the death of the Paschal lamb is. symbol of the redemption, by which the death penalty due from one is paid by another, so the eating of it is. figure of the participation of pardon, acceptance, and blessedness, consequent upon the atonement.

Roast with fire.

Roasted, because the whole meal was hurried--a hasty meal, on the eve of departure, and the roasting in the fire was more speedy than boiling.

And unleavened bread.

This symbolized three things--the haste which did not permit bread to rise; their sufferings in Egypt, on account of which it was called the bread of affliction (Deuteronomy 16:3); and lastly, purity, since fermentation is incipient putrefaction, and leaven is. symbol of impurity.

Bitter herbs.

A symbol of their bitter bondage.
