Mark 1:44-45

and He *said to him, “See that you say nothing to anyone; but go, show yourself to the priest and offer for your cleansing what Moses commanded, as a testimony to them.” But he went out and began to proclaim it freely and to spread the news around, to such an extent that Jesus could no longer publicly enter a city, but stayed out in unpopulated areas; and they were coming to Him from everywhere.
