Now if a child can be circumcised on the Sabbath so that the law of Moses may not be broken, why are you angry with me for healing the whole man on the Sabbath?
The Messiah Jesus is Lord of the Sabbath. He told us to rest, and to keep the day of rest Holy. But we can also, and shall also do good. The Jewish people had been told by some of their Rabbis that is was unlawful to heal on the Sabbath. The Messiah rebuked them.
