Thou shall not offer the blood of my sacrifice with leavened bread,.... This belongs to the feast of the passover; for, as all the Jewish writers agree, this sacrifice is the sacrifice of the passover, as it is sometimes called, see Exodus 12:27 now when the paschal lamb was killed, and its blood shed, and its flesh eaten, there was to be no leaven along with it; it was to be eaten with unleavened bread, and there was to be no leaven in their houses at this time; nay, it was not to be slain until all was removed: this was the first thing the Jews did, as soon as the fourteenth day was come, to search for leaven, remove and burn it; and this sense of the law is confirmed by the Targum of Jona…

Exodus 23:14-17
14. Three times thou shalt keep a feast unto me in the year.
14. Ter festum celebrabis mihi unoquoque anno.
15. Thou shalt keep the feast of unleavened bread: (thou shalt eat unleavened bread seven days, as I commanded thee, in the time appointed of the month Abib; for in it thou camest out from Egypt: and none shall appear before me empty:)
15. Solennitatem azymorum custodies: septem diebus comedes infermentata, quemadmodum praecepi tibi tempore mensis Abib: quia in eo egressus es ex Aegypto: neque conspicientur coram me vacui.
16. And the feast of harvest, the firstfruits of thy labours, which thou hast sown in the field: and the feast of ingathering, which is in the…

The blessing attending their appearing before the Lord was dependent upon the feasts being kept in the proper way, by the observance of the three rules laid down in Exo 23:18 and Exo 23:19. "Thou shalt not offer the blood of My sacrifice upon leavened bread." על upon, as in Exo 12:8, denoting the basis upon which the sacrifice was offered. The meaning has been correctly given by the early commentators, viz., "as long as there is any leavened bread in your houses," or "until the leaven has been entirely removed from your houses." The reference made here to the removal of leaven, and the expression "blood of My sacrifice," both point to the paschal lamb, which was regarded as the sacrifice of…

לא תזבח על חמץ וגו׳ means, you shall not sacrifice the Passover-lamb on the fourteenth day of Nisan before you have removed the leavened bread from your house (Mekhilta). (This verse is to be connected with v. 15).
ולא ילין חלב חגי NEITHER SHALL THE FAT OF MY SACRIFICE REMAIN away from the altar (cf. the Targum).
UNTIL MORNING. One might think, however, that the meaning is, that it shall not remain overnight on the altar and that the sacrifice would therefore become invalid even through the fat remaining overnight on the “wood-pile” of the altar! Scripture, however, states, (Leviticus 6:2) “[This is the law of the burnt-offering; it is that which may go up] on the fire-place of the altar a…
