In Luke 13:10-17, Christ heals another chronically ill person on the Sabbath. This time, though, He did not wait for anyone to ask Him questions. The episode plainly discloses the redeeming and liberating intention of God's Sabbath. When Jesus says, "You are loosed," the ruler of the synagogue reacts immediately because to him the Sabbath meant rules to obey rather than people to love.
Jesus replies in verses 15-16 by emphasizing the Sabbath principle:
The Lord then answered him and said, "Hypocrite! Does not each one of you on the Sabbath loose his ox or donkey from the stall, and lead it away to water it? So ought not this woman, being a daughter of Abraham, whom Satan has bound—think of it—for eighteen years, be loosed from this bond on the Sabbath?"
Christ makes a play on words here. He uses the same verb, "loose," to describe the ox and donkey as He does the woman being "loosed" from Satan through healing.
Jesus acts against the tradition of the Pharisees, but no where challenges the binding obligation of keeping the Sabbath. Rather, His example shows that we should make merciful evaluations to help others cast off their heavy burdens. He argues for living the true values.
