What does the Bible say about the Sabbath and healing?

In Luke 14, Jesus healing a man with dropsy on the Sabbath demonstrates the importance of mercy over rigid adherence to the law. The Pharisees focused on the rules surrounding the Sabbath but failed to see that the intent of the Sabbath was to do good and show mercy. Isaiah 58:13-14 supports this view, highlighting that observing the Sabbath includes honoring God, which involves acts of kindness. Jesus himself embodies the Sabbath as our rest, providing healing and salvation, thus showing that mercy is always allowed.
