(And unto those who are Jews) those who stirred away from Islam, i.e. the Jews (We have forbidden that which We have already) before this surah, and specifically in surah al-An'am (related unto thee) that which We have named to you. (And We wronged them not) because of what We forbade them of meats and fats, (but they were wont to wrong themselves) they were wont to harm, i.e. He forbade them those things because of their sins.
