When Jesus referred to the woman in Luke 13 as a “daughter of Abraham” it was not a reference to a “covenant of healing”. He was contrasting her to his previous reference to the donkey or ox that they would assist. It was if He had said: You know to water your donkey or ox on the Sabbath, would you not help this daughter of Abraham?
The context is not about healing. It is about the Sabbath.
the_Watchman there is more than one revelation, so if that’s how you see it fine. But, she did have a covenant of healing with God because she was a seed of Abraham. Thanks!
