The Talmudic Debate Over Not Burning Leftover Meat on the Holy Day

One does not kindle a lamp with oil of burning [oil from a defiled offering, on a festival]. From where are these words derived? Hezekiah said, and likewise the school of Hezekiah taught: The verse says, "And you shall let none of it remain until morning," for there is no need for the verse to say "until morning" [since the prohibition is already stated]; so why does the verse say "until morning"? Scripture comes to provide a second morning for its burning. Abaye said: The verse says, "the burnt offering of each Sabbath in its own Sabbath" (Numbers 28:10), and not the burnt offering of a weekday on a festival. Rava said: The verse says (Exodus 12:16), "that alone may be done for you" - "that" and not its preparations; "alone" and not circumcision performed out of its proper time. Rav Ashi said: The verse says (Leviticus 23:3), "a Sabbath of complete rest," a positive command, so that the festival becomes both a positive and a negative command, and a positive command does not override a command that is both negative and positive. The bones and the sinews are burned on the sixteenth. And let a positive command come and override a negative one. Hezekiah said: "And you shall let none of it remain until morning," and so forth. Abaye said: The verse says, "the burnt offering of each Sabbath in its own Sabbath," and so forth. Rava said: The verse says, "a Sabbath of complete rest," and so forth.
