2 Corinthians 6

10. The "as" no longer is used to express the opinion of his adversaries, but the real state of him and his fellow laborers.
making many rich--Spiritually ( 1 Corinthians 1:5 ), after the example of our Lord, who "by His poverty made many rich" ( 2 Corinthians 8:9 ).
having nothing--Whatever of earthly goods we have, and these are few, we have as though we had not; as tenants removable at will, not owners ( 1 Corinthians 7:30 ).
possessing all things--The Greek implies firm possession, holding fast in possession (compare 1 Corinthians 3:21 1 Corinthians 3:22 ). The things both of the present and of the future are, in the truest sense, the believer's in possession, for he possesses them all in Christ, his lasting possession, though the full fruition of them is reserved for the future eternity.

11. mouth . . . open unto you--I use no concealment, such as some at Corinth have insinuated ( 2 Corinthians 4:2 ). I use all freedom and openness of speech to you as to beloved friends. Hence he introduces here, "O Corinthians" (compare Philippians 4:15 ). The enlargement of his heart towards them ( 2 Corinthians 7:3 ) produced his openness of mouth, that is, his unreserved expression of his inmost feelings. As an unloving man is narrow in heart, so the apostle's heart is enlarged by love, so as to take in his converts at Corinth, not only with their graces, but with their many shortcomings (compare 1 Kings 4:29 , Psalms 119:32 , Isaiah 60:5 ).

12. Any constraint ye feel towards me, or narrowness of heart, is not from want of largeness of heart on my part towards you, but from want of it on your part towards me.
bowels--that is, affections (compare 2 Corinthians 12:15 ).
not straitened in us--that is, for want of room in our hearts to take you in.

13. Translate, "As a recompense in the same kind . . . be enlarged also yourselves" [ELLICOTT]. "In the same way" as my heart is enlarged towards you ( 2 Corinthians 6:11 ), and "as a recompense" for it ( Galatians 4:12 ).
I speak as unto my children--as children would naturally be expected to recompense their parents' love with similar love.

14. Be not--Greek, "Become not."
unequally yoked--"yoked with one alien in spirit." The image is from the symbolical precept of the law ( Leviticus 19:19 ), "Thou shalt not let thy cattle gender with a diverse kind"; or the precept ( Deuteronomy 22:10 ), "Thou shalt not plough with an ox and an ass together." Compare Deuteronomy 7:3 , forbidding marriages with the heathen; also 1 Corinthians 7:39 . The believer and unbeliever are utterly heterogeneous. Too close intercourse with unbelievers in other relations also is included ( 2 Corinthians 6:16 , 1 Corinthians 8:10 , 10:14 ).
fellowship--literally, "share," or "participation."
righteousness--the state of the believer, justified by faith.
unrighteousness--rather, as always translated elsewhere, "iniquity"; the state of the unbeliever, the fruit of unbelief.
light--of which believers are the children ( 1 Thessalonians 5:5 ).

15. Belial--Hebrew, "worthlessness, unprofitableness, wickedness." As Satan is opposed to God, and Antichrist to Christ; Belial being here opposed to Christ, must denounce all manner of Antichristian uncleanness [BENGEL].
he that believeth with an infidel--Translate, "a believer with an unbeliever."

16. agreement--accordance of sentiments (compare 1 Kings 18:21 , Ephesians 5:7 Ephesians 5:11 ).
the temple of God--that is, you believers ( 1 Corinthians 3:16 , 6:19 ).
with idols--Compare Dagon before the ark ( 1 Samuel 5:2-4 ).
as--"even as God said." Quotation from Leviticus 26:12 , Jeremiah 31:33 , 32:38 , Ezekiel 37:26 Ezekiel 37:27 ; compare Matthew 28:20 , John 14:23 .
walk in them--rather, "among them." As "dwell" implies the divine presence, so "walk," the divine operation. God's dwelling in the body and soul of saints may be illustrated by its opposite, demoniacal possession of body and soul.
my people--rather, "they shall be to me a people."

17. Quoted from Isaiah 52:11 , with the freedom of one inspired, who gives variations sanctioned by the Holy Spirit.
be ye separate--"be separated" ( Hosea 4:17 ).
touch not the unclean thing--rather, "anything unclean" ( 2 Corinthians 7:1 , Micah 2:10 ). Touching is more polluting, as implying participation, than seeing.
receive you--The Greek implies, "to myself"; as persons heretofore out of doors, but now admitted within ( 2 Corinthians 5:1-10 ). With this accords the clause, "Come out from among them," namely, so as to be received to me. So Ezekiel 20:41 , "I will accept you"; and Zephaniah 3:19 , "gather her that was driven out." "The intercourse of believers with the world should resemble that of angels, who, when they have been sent a message from heaven, discharge their office with the utmost promptness, and joyfully fly back home to the presence of God" ( 1 Corinthians 7:31 , 1 Corinthians 5:9 1 Corinthians 5:10 ).

18. Translate, "I will be to you in the relation of a Father, and ye shall be to me in the relation of sons and daughters." This is a still more endearing relation than ( 2 Corinthians 6:16 ), "I will be their God, and they . . . My people." Compare the promise to Solomon ( 1 Chronicles 28:6 , Isaiah 43:6 , Revelation 21:3 Revelation 21:7 , Jeremiah 31:1 Jeremiah 31:9 ).
Lord Almighty--The Lord the Universal Ruler: nowhere else found but in Revelation. The greatness of the Promiser enhances the greatness of the promises.
