Matthew 8:1–4 (NLT)

Large crowds followed Jesus as he came down the mountainside. 2 Suddenly, a man with leprosy approached him and knelt before him. “Lord,” the man said, “if you are willing, you can heal me and make me clean.”

3 Jesus reached out and touched him. “I am willing,” he said. “Be healed!” And instantly the leprosy disappeared. 4 Then Jesus said to him, “Don’t tell anyone about this. Instead, go to the priest and let him examine you. Take along the offering required in the law of Moses for those who have been healed of leprosy. This will be a public testimony that you have been cleansed.”

Matthew 8:1–2 (NLT)

Matthew 4:23–25 (NLT)

23 Jesus traveled throughout the region of Galilee, teaching in the synagogues and announcing the Good News about the Kingdom. And he healed every kind of disease and illness. 24 News about him spread as far as Syria, and people soon began bringing to him all who were sick. And whatever their sickness or disease, or if they were demon possessed or epileptic or paralyzed—he healed them all. 25 Large crowds followed him wherever he went—people from Galilee, the Ten Towns, Jerusalem, from all over Judea, and from east of the Jordan River.

William Barclay - "There never has been any disease which so separated a man from his fellow-men as leprosy did." 

• Miriam (Numbers 12:10).
• Elisha's servant Gehazi (2 Kings 5:27).
• King Uzziah (2 Chronicles 26:16-21).

FIRST, the man "came".

SECOND, the man came reverently.

THIRD, The man acknowledged Jesus' power.

A first reason would be out of reverence to His Father.

A second reason would be out of concern for the man himself.

A third reason would have been out of concern for the priests.

A fourth reason would be out of concern for Jesus' own ministry.
