The "cow-keeper"-story?

My person remembers a possible common know story about a Brahman collecting as much as possible cow's leading to sorrows for poor. The Sublime Buddha approached him one day, gave a talk and later he released the cows. It might be that's just a later tale not found in the scripts, my person just does not remember where having been come across aside in an illustrated "Children"-book. Good if one likes to share messages on livelihood. *[Note that this isn't given for stacks, exchange, other world-binding trades but for release from this wheel]*
