A Midrash interpreted Psalm , "The Lord lets loose the prisoners," to read, "The Lord permits the forbidden," and thus to teach that what God forbade in one case, God permitted in another. God forbade the abdominal fat of cattle (in ), but permitted it in the case of beasts. God forbade consuming the sciatic nerve in animals (in ) but permitted it in fowl. God forbade eating meat without ritual slaughter (in ) but permitted it for fish. Similarly, Rabbi Abba and Rabbi Jonathan in the name of Rabbi Levi taught that God permitted more things than God forbade. For example, God counterbalanced the prohibition of pork (in and ) by permitting mullet (which some say tastes like pork).
