For example, in another instance of a man who had been an invalid for 38 years who waited for the movement of the water in a pool in the Gospel of John (5:2–15) and whose name remains unknown, Jesus cures that sick person and warns him about the consequences in case he reverts to doing things that brought him to the condition of infirmity of which he's now restored (5:14), as yet he might have had inclination towards sin. Unlike him, healed Bartimaeus follows Jesus immediately, which led the evangelist Mark to include his name in the narrative. Bartimaeus also teaches us a Jesus Prayer, "Jesus, Son of David, have mercy on me!", and, its result, an acquiring spiritual eyesight, the sign of which was his restored ability to see.
