"Is it lawful to heal on the Sabbath, or not?" (v3). On the Sabbath, Jesus was dining at the house of “a ruler of the Pharisees,” the religious group who were extremely careful to avoid breaking Sabbath rules. These religiously correct people were watching Jesus carefully to see what he would do about the man who was sick (v2). Jesus pointed out that they would all rescue an animal on the Sabbath (a work-like action), implying therefore that it was ridiculous to ignore the pain of a human being.
“He took him and healed him” (v4). It’s not enough to avoid doing wrong; Jesus calls us to join Him in extending mercy, compassion, and help to those in need
