Mark 1:45

But he went out, and began to publish it much, and to blaze abroad the matter, insomuch that Jesus could no more openly enter into the city, but was without in desert places; and they came to Him from every quarter.

Here is a matter which might seem strange at first glance. Speaking to the former leper in a most severe manner, assuming a threatening aspect, He thrust him away, with the injunction to tell no man about the miracle, but to follow the command of the Levitical purification strictly, Leviticus 13:1; Leviticus 14:1. The bringing of his sacrifice was to be a witness, a testimony to all men, that he really had been cleansed of his leprosy. The reasons for this behavior of the Lord are evident from the entire story, in comparison with the previous text. The Word of the Gospel which He preached was the most important thing in the eyes of the Lord. People should seek Him for the sake of that Word. Publicity resulting from His healing the sick and cleansing the lepers might bring many that would care nothing for the preaching and thus hinder His Messianic labors. Then also, the Lord wanted to avoid unpleasantness, in case the priest should find out about His healing the leper before the man actually appeared to be adjudged clean. But the man, in the fullness of his joy, disregarded the Lord's command and, by publishing broadcast the fact of his having been healed, really added to the Lord's anxieties and labors. For now people came swarming from all sides, insomuch. that Jesus could no longer go into the city, but was obliged to stay out in lonely, desert places, and even there they found Him, coming from all parts of Galilee.

Summary. John's ministry prepared the way for the Lord, who thereupon, after His baptism and the temptation in the wilderness, entered upon His labors in Galilee, called four men to be His disciples, taught in the synagogue and cast out an unclean spirit, healed Simon's mother-in-law and many other sick people, made a preaching trip through Galilee, and healed a leper.
