V.34 It is good to notice the expression “when ye come into the land,” not “if.” It was absolutely certain, yet Israel had to wander for 40 years in the wilderness because they didn’t believe this statement (See Num 13 -14). Are we enjoying our heavenly life while we’re still here on earth?
V.33-48 Leprosy in the house. A pure house was necessary. Let us apply the “house” to two scriptures (1 Tim. 3:15; 2 Tim. 2:20), Christians gathered to the name of the Lord Jesus Christ in a city. The “house” must be kept pure of every evil — doctrinal, ecclesiastical or moral. As a collective testimony, gathered together by the Holy Spirit to maintain His unity (Eph. 4:3) truth must be kept, error must be removed.
V.35-39 The owner of the house was suspicious that something was wrong. He must go to the priest, who makes careful investigation. He waits for 7 days, then returns to see if conditions have changed.
V.40-42 He finds that indeed there is a plague there, so he orders the particular stones removed and the walls scraped. New stones are put in their place. There was to be great care taken.
V.43-47 If the plague returns, the leprosy is announced and the house destroyed totally. Notice where the stones etc. are taken.
V.48 But if the plague has not returned, the priest pronounces the house clean.
V.49-53 Then the house needs the same kind of cleansing that was used in verses 4-7 for the man which was cleansed.
All this teaches us spiritual lessons. Whether in an individual (yesterday’s verses) or collectively (today’s) they both need to put out of their lives all evil! 1 Corinthians 5 is instructive in the New Testament on the same subject. May each of us take this to heart! It is what God is telling us.
