The Gospel of Luke describes a miracle that Jesus performed on the Sabbath, healing a man who suffered from a condition that caused an abnormal swelling of his body:
Then he asked them, "If one of you has a child or an ox that falls into a well on the Sabbath day, will you not immediately pull it out?" And they had nothing to say.
-Luke 14:1-6, NIV translation.
The Pharisees were among the prominent religious leaders in the land of Israel during the time of Jesus. Some of them strongly opposed Jesus and plotted against him, trying to entrap him in situations that would cause harm to him.
The man who Jesus healed might have been suffering from Dropsy, which is also known as Edema. It is an abnormal condition in which fluid accumulates under a person's skin, in some areas of their body, such as in the legs. The condition, which can be very dangerous, requires medical attention from a doctor.
