Midrash sur L’Exode 30:28

R. Eliezer says: If the Paschal lamb, which is not forbidden to be cooked (raw), is forbidden to be eaten (raw, viz. Shemoth 12:9), then meat with milk, which is forbidden to be cooked, how much more so should it be forbidden to be eaten! — (No,) this is refuted by the compounding of the incense, whose compounding is forbidden (viz. Shemoth 30:28) and not its inhaling. Do not wonder, then, if meat with milk, even though it is forbidden to be cooked would be permitted to be eaten. It must, therefore, be written "You shall not eat it" — to include (as forbidden to be eaten) meat with milk.
