8 And they shall eat the flesh in that night, roast with fire, and unleavened bread; and with bitter herbs they shall eat it.

9 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.

10 And ye shall let nothing of it remain until the morning; and that which remaineth of it until the morning ye shall burn with fire.

11 And thus shall ye eat it; with your loins girded, your shoes on your feet, and your staff in your hand; and ye shall eat it in haste: it is the Lord’s passover.

God provided further instructions for how the Passover meal was to be prepared. First, the lamb was to be roasted, not boiled, and all in a single piece: head, legs, and edible organs included. Other commentators have pointed out that roasting would have been the quickest way to prepare the food, beginning a theme of haste that we will see continued in the other details. Also, roasting is simpler than boiling, especially when it is an entire lamb that has to be cooked, and therefore more accessible to the simplest and poorest of the Israelites.

Secondly, with the lamb the Israelites were to have unleavened bread and bitter herbs. Unleavened bread is also a sign of haste, as they were not allowing time for the bread to rise. Bitter herbs are also quick to assemble and prepare. These two items also represent hardship, as leavened bread and sweeter herbs would be more pleasant to the taste, but the rougher alternatives are a more fitting match to the bondage that Israel had suffered for generations.

Finally, all of the food was to be consumed in a single night, and any leftovers burned with fire. A camp that is on the move, that needs to flee in the morning, has no purpose for leftovers and so it is tossed in the fire. This idea of being ready to move is further reinforced by the instruction that they eat dressed, with their shoes on, and the staff in their hands.

All this suddenness and haste and living by simple means is also reflected by Jesus’ later instruction that “no one, having put his hand to the plow, and looking back, is fit for the kingdom of God.” Jesus taught his disciples that when one was called to the work there was not be any excuse or delay. One had to be ready to drop all and move as directed. Jesus further told his disciples that when they preached the gospel, they were not to pack food or extra clothing, but to travel with the absolute minimum, trusting God to provide the rest. All of this echoes back to the ritual of the Israelites on the Passover. The true disciples and the chosen people are to be in a state of constant readiness, quick to move at the command of their Lord, content to cast everything aside to follow.
