John Gill Bible Commentary

And great multitudes followed him,.... The Persic version adds, "of the sick and diseased"; but all that followed him were not such, though some were: these came not only from Galilee, but from the adjacent parts, from the country beyond Jordan, and the coasts of Judea, where he had been formerly; and who resort to him again, as Mark observes; and whom, according to his usual manner, he taught and instructed in the knowledge of divine things, and confirmed his doctrines by miracles: and he healed them there; in the above mentioned places, even as many of them as were sick and diseased.
