Jesus uses a question to respond to the Pharisees. He is challenging them to think about what kind of work they do on the Sabbath. AT: "Every one of you, if you only had one sheep ... would grab the sheep and lift it out." (See: [[rc://en/ta/man/translate/figs-rquestion]])
The phrase "how much more" adds emphasis to the statement. AT: "Obviously, a man is much more valuable than a sheep!" or "Just think about how much more important a man is than a sheep"
