I got mouths to feed, unnecessary beef is more cows to breed
“I got mouths to feed” — GZA has just established that he has lots of seeds (those he is responsible for, his literal and metaphorical children), and he is loath to see their lives “wasted” in the ghetto cycle of beef and violence. He has to take care of them, and he doesn’t want to raise any more beef (street violence) than is strictly necessary to do so.
Very complex metaphorical tangle — but as brilliant as anything GZA came up with in his prime.
