What does the Bible say about Jesus healing on the Sabbath?

In Mark 3, Jesus confronts the Pharisees regarding legalistic interpretations of the Sabbath. He demonstrates that doing good, such as healing, is consistent with the purpose of the Sabbath, which was created for humanity's benefit, not to be a burden. The passage illustrates that Jesus is the Lord of the Sabbath, emphasizing that mercy and compassion should take precedence over rigid religious rules. This event serves to reveal the hardness of the Pharisees' hearts, who valued their traditions over God's intent for the Sabbath.
