LXX Deuteronomy 16:7
5 You shall not be able to offer the Passover in any of your cities that the Lord your God has given you; 6 rather into the place that the Lord your God may choose to have his name invoked, in that place you shall offer the Passover in the evening to the setting of the sun, at the time that you came out of Egypt. 7 And you shall boil and roast and eat it in the place where the Lord your God may choose it, and you shall return in the morning and go into your houses. 8 Six days you shall eat unleavened bread, but the seventh day, the final day, there shall be a festival to the Lord your God; you shall not do any work in it; you shall only do that which is necessary for life. 9 Seven weeks you shall count for yourself when you have begun your sickle upon the harvest; you shall begin to count seven weeks. The Feast of Weeks

Notes and References
"... in Chronicles, the tôrah (“law”) is a term used to give legitimacy to post-exilic religious practices such as the maintenance and organization of the temple, which are omitted in the Pentateuch ... For instance, Chronicles lowers the age at which a Levite begins to serve in the temple from thirty to twenty (1 Chronicles 23:24-27; contrast this with 1 Chronicles 23:3 and Numbers 4:23) and requires ten lampstands (2 Chronicles 4:7, 20) amongst the temple furnishings instead of the one six-branched lampstand sufficient for the tabernacle (Exodus 25:32; 37:17-23). Moreover, Chronicles harmonizes the conflicting Passover regulations about the preparation of the Passover animal. In Exodus 12:9, it is to be roasted and not eaten raw or boiled, while in Deuteronomy 16:7, it is to be boiled. 2 Chronicles 35:13 combines the two: “And they boiled the Passover lamb in the fire according to the decision (mišpaṭ)”; mišpaṭ here must mean “according to the interpretive tradition” ..."
