Deuteronomy 16:7
5 You may not sacrifice the Passover in just any of your villages that the Lord your God is giving you, 6 but you must sacrifice it in the evening in the place where he chooses to locate his name, at sunset, the time of day you came out of Egypt. 7 You must boil13 and eat it in the place the Lord your God chooses; you may return the next morning to your tents. 8 You must eat bread made without yeast for six days. The seventh day you are to hold an assembly for the Lord your God; you must not do any work on that day. 9 You must count seven weeks; you must begin to count them from the time you begin to harvest the standing grain.
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.
Notes and References
"... In the 1980s, scholars delineated the dynamics of what Michael Fishbane termed the “legal blend” in postexilic biblical literature. This referred to the oft found phenomenon in Ezra-Nehemiah and Chronicles whereby the practice of a law is expressed as a conflation of two earlier diverging iterations of the law as found in the legal corpora of the Pentateuch. Perhaps the most heralded of these has been the Chronicler’s description of the paschal sacrifice in the time of Josiah. Exodus 12:9 is explicit that the paschal sacrifice is to be roasted in fire (שא ילצ), and may not be boiled in water. The author of Deuteronomy 16:7, however, sought to align the paschal sacrifice with other cultic offerings, and prescribed boiling (תלשבו). The Chronicler created a legal blend of these two received traditions by conflating lexical elements of each statement of the law in his description of the paschal offering in the time of Josiah (2 Chronicles 35:13). The conflation is surprising, because the two original iterations of the law seem mutually exclusive in their provisions ..."
