Mark 1:44-45

44saying to him, “See that you tell no one anything [about this]; but go, show yourself to the priest and offer for your purification what Moses commanded, as proof to them [that you are really healed].”

45But he went out and began to proclaim it freely and to spread the news [of his healing], to such an extent that Jesus could no longer openly enter a city [where He was known], but stayed out in the unpopulated places; yet people were still coming to Him from everywhere.
