Camp, or city, unless some great man, like king Ozias, might be permitted to dwell there in a house, secluded from all society, 4 Kings xv. 5. — 2 Paralipomenon xxvi. 21.

Matthew Henry Commentary on the Whole Bible (Complete) (Matthew Henry)

2. He must then be shut out of the camp, and afterwards, when they came to Canaan, out of the city, town, or village, where he lived, and dwell alone (v. 46), associating with none but those that were lepers like himself. When king Uzziah became a leper, he was banished from his palace, and dwelt in a separate house, 2 Chron 26 21. And see 2 Kings 7 3. This typified the purity which ought to be preserved in the gospel church, by the solemn and authoritative exclusion of scandalous sinners, that hate to be reformed, from the communion of the faithful. Put away from among yourselves that wicked person, 1 Cor 5 13.

Matthew Henry Commentary on the Whole Bible (Concise) (Matthew Henry)

Verses 45-46 When the priest had pronounced the leper unclean, it put a stop to his business in the world, cut him off from his friends and relations, and ruined all the comfort he could have in the world. He must humble himself under the mighty hand of God, not insisting upon his cleanness, when the priest had pronounced him unclean, but accepting the punishment. Thus must we take to ourselves the shame that belongs to us, and with broken hearts call ourselves "Unclean, unclean;" heart unclean, life unclean; unclean by original corruption, unclean by actual transgression; unclean, therefore deserving to be for ever shut out from communion with God, and all hope of happiness in him; unclean, therefore undone, if infinite mercy do not interpose. The leper must warn others to take heed of coming near him. He must then be shut out of the camp, and afterward, when they came to Canaan, be shut out of the city, town, or village where he lived, and dwell with none but those that were lepers like himself. This typified the purity which ought to be in the gospel church.
