Bede, on Exod 12:11

“And thus you shall eat it: you shall gird your reins, and you shall have shoes on your feet, holding staves in your hands, and you shall eat in haste: for it is the Phase (that is the Passage) of the Lord.”

“Passover means "passing over." It derives its ancient name from the Lord's passing over on this [day] through Egypt, striking the firstborn of the Egyptians and freeing the children of Israel, and from the children of Israel's passing over on that night from their slavery in Egypt in order that they might come to the land which had once been promised to their heirs as a land of peace. Mystically it signifies that on this [day] our Lord would pass over from this world to his Father. Following his example, the faithful, having cast off temporal desires and having cast off their slavery to vices by their continual practice of the virtues, should pass over to their promised heavenly fatherland.”
