Exodus 12:9
7 They will take some of the blood and put it on the two side posts and top of the doorframe of the houses where they will eat it. 8 They will eat the meat the same night; they will eat it roasted over the fire with bread made without yeast and with bitter herbs. 9 Do not eat it raw or boiled in water, but roast it over the fire with its head, its legs, and its entrails. 10 You must leave nothing until morning, but you must burn with fire whatever remains of it until morning. 11 This is how you are to eat it—dressed to travel, your sandals on your feet, and your staff in your hand. You are to eat it in haste. It is the Lord’s Passover.
2 Chronicles 35:13
11 They slaughtered the Passover lambs and the priests splashed the blood, while the Levites skinned the animals. 12 They reserved the burnt offerings and the cattle for the family divisions of the people to present to the Lord, as prescribed in the scroll of Moses. 13 They cooked the Passover sacrifices over the open fire as prescribed and cooked the consecrated offerings in pots, kettles, and pans. They quickly served them to all the people. 14 Afterward they made preparations for themselves and for the priests, because the priests, the descendants of Aaron, were offering burnt sacrifices and fat portions until evening. The Levites made preparations for themselves and for the priests, the descendants of Aaron. 15 The musicians, the descendants of Asaph, manned their posts, as prescribed by David, Asaph, Heman, and Jeduthun the king’s prophet. The guards at the various gates did not need to leave their posts, for their fellow Levites made preparations for them.
Notes and References
"... Cooking the Passover lamb with fire is an attempt to harmonize divergent directives in the Pentateuch. In Exodus 12:8, the Israelites are instructed to eat the Passover lamb roasted over the fire, whereas in the next verse they are forbidden co eat it raw or boiled in water but roasted over the fire. ln Deuteronomy 16:7, they are ordered to cook it. As Ehud Ben Zvi notes, "The Chronicler expands the semantic meaning of 'boil' to include not only boiling in water or milk but also 'boiling' in fire, which in practice is roasting. This interpretation should not obscure the fact that the Chronicler was trying to harmonize the two conflicting Pentateuchal regulations, and in fact there is no biblical ordinance for this harmonization ..."
