Leviticus 13:9

When the plague of leprosy is in a man,.... He has all the signs of it, and it is pretty manifest both to himself and others that it is upon him;

then he shall be brought unto the priest; by his friends and neighbours, if he is not willing to come of himself: a sinner insensible of the leprosy of sin, and of his unclean and miserable state through it, has no will to come to Christ the great High Priest for cleansing; but one that is sensible of it, and of Christ's ability to help and cleanse him, will come freely and gladly, and importunately seek to him for it; though indeed such an one is brought by powerful and efficacious grace to him, yet not against, but with his full will; see John 5:40; compare with this Matthew 8:1.
