Origen, on Exod 12:8

“And they shall eat the flesh that night roasted at the fire, and unleavened bread with wild lettuce.”

“Then too the unleavened bread is commanded to be eaten with bitter herbs; nor is it possible to attain the promised land unless we pass through bitterness. For just as physicians put bitter substances in medicines with a view to the health and healing of the infirm, so also the Physician of our souls with a view to our salvation has wished us to suffer the bitterness of this life in various temptations. [He knows] that the end of this bitterness gains the sweetness of salvation for our soul, just as, on the contrary, the end of the sweetness found in corporeal pleasure, as the example of that rich man teaches, brings a bitter end: torments in hell.”
