John Gill Commentary Matthew 19:2

"and great multitudes followed him; and he healed them there." — Matthew 19:2 (ASV)

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.
