The Pharisees ask Jesus a question to condemn him. This can be translated as a statement. Alternate translation: "Look! They are breaking the Jewish law concerning the Sabbath." (See: [[rc://en/ta/man/translate/figs-rquestion]])
"Look at this" or "Listen." This is a word used to get the attention of someone to show them something. If there is a word in your language that is used to draw a person's attention to something, you could use that here.
