Stretch forth thy hand. c And he did so: a he stretched it forth; and it b his hand was restored.
There’s something that boggles my mind here: the pharisees were trying to catch Jesus breaking the sabbath laws, and so they entice him to heal a man so that they can claim he is doing “work” on the sabbath. The fact that they are not just astounded by his miraculous works is surprising.
So Jesus pulls a swerve on them here, because he doesn’t actually do anything to heal the man, just says “stretch out your hand.” The man does so and his hand is healed. Jesus didn’t touch him, or wave his wand, or anything like that, just spoke to him.
