1 Corinthians, Chapter 5, verses 9-13
7 The old leaven is to be purged out, 10 Heinous offenders are to be shamed and avoided1 Corinthians, Chapter 6, verses 1-11
1 The Corinthians must not vex their brethren in going to law with them, 6 especially under infidels, 9 The unrighteous shall not inherit the kingdom of God6
6:1 The unjust - The heathens. A Christian could expect no justice from these. The saints - Who might easily decide these smaller differences in a private and friendly manner.
6:2 Know ye not - This expression occurs six times in this single chapter, and that with a peculiar force; for the Corinthians knew and gloried in it, but they did not practise.That the saints - After having been judged themselves. Shall judge the world - Shall be assessors with Christ in the judgment wherein he shall condemn all the wicked, as well angels as men, Mat 19:28 Rev 20:4.
6:4 Them who are of no esteem in the church - That is, heathens, who, as such, could be in no esteem with the Christians.
6:5 Is there not one among you, who are such admirers of wisdom, that is wise enough to decide such causes?
6:7 Indeed there is a fault, that ye quarrel with each other at all, whether ye go to law or no. Why do ye not rather suffer wrong - All men cannot or will not receive this saying.Many aim only at this, "I will neither do wrong, nor suffer it." These are honest heathens, but no Christians.
6:8 Nay, ye do wrong - Openly. And defraud - Privately.O how powerfully did the mystery of iniquity already work!
6:9 Idolatry is here placed between fornication and adultery, because they generally accompanied it. Nor the effeminate - Who live in an easy, indolent way; taking up no cross, enduring no hardship. But how is this? These good - natured, harmless people areranked with idolaters and sodomites! We may learn hence, that we are never secure from the greatest sins, till we guard against those which are thought the least; nor, indeed, till we think no sin is little, since every one is a step toward hell.
6:11 And such were some of you: but ye are washed - From those gross abominations; nay, and ye are inwardly sanctified; not before, but in consequence of, your being justified in the name - That is, by the merits, of the Lord Jesus, through which your sins are forgiven. And by the Spirit of our God - By whom ye are thus washed and sanctified.
Matthew, Chapter 13, verses 54-58
53 and how Christ is contemned of his own countrymen13
13:54 Whence hath HE - Many texts are not understood, for want of knowing the proper emphasis; and others are utterly misunderstood, by placing the emphasis wrong. To prevent this in some measure, the emphatical words are here printed in capital letters. Mar 6:1; Luk 4:16, Luk 4:22.
13:55 The carpenter's son - The Greek, word means, one that works either in wood, iron, or stone. His brethren - Our kinsmen. They were the sons of Mary, sister to the virgin, and wife of Cleophas or Alpheus. James - Styled by St. Paul also, the Lord's brother, Gal 1:19.Simon - Surnamed the Canaanite.
13:57 They were offended at him - They looked on him as a mean, ignoble man, not worthy to be regarded. Joh 4:44; Luk 7:23.
13:58 He wrought not many mighty works, because of their unbelief - And the reason why many mighty works are not wrought now,is not, that the faith is not every where planted; but, that unbelief every where prevails.

5:9 I wrote to you in a former epistle - And, doubtless, both St. Paul and the other apostles wrote many things which are not extant now. Not to converse - Familiarly; not to contract any intimacy or acquaintance with them, more than is absolutely necessary.
5:10 But I did not mean that you should altogether refrain from conversing with heathens, though they are guilty in some of these respects. Covetous, rapacious, idolaters - Sinners against themselves, their neighbour, God. For thenye must go out of the world - Then all civil commerce must cease.So that going out of the world, which some account a perfection, St. Paul accounts an utter absurdity.
5:11 Who is named a brother - That is, a Christian; especially if a member of the same congregation. Rapacious - Guilty of oppression, extortion, or any open injustice. No,not to eat with him - Which is the lowest degree of familiarity.
5:12 I speak of Christians only. For what have I to do to judge heathens? But ye, as well as I, judge those of your own community.
5:13 Them that are without God will judge - The passing sentence on these he hath reserved to himself. And ye will take away that wicked person - This properly belongs to you.
