A 3 And I wrote this same unto you, lest, when I came, I should have sorrow from them of whom I ought to rejoice; having confidence in you all, that my joy is the joy of you all.(4a) For out of much affliction and anguish of heart I wrote unto you with many tears;
B (4b) not that ye should be grieved, but that ye might know the love which I have more abundantly unto you.
C (5) But if any have caused grief, he hath not grieved me, but in part: that I may not overcharge you all.
D (6-7a) Sufficient to such a man is this punishment, which was inflicted of many. So that contrariwise ye ought rather to forgive him, and comfort him,
C’ (7b) lest perhaps such a one should be swallowed up with overmuch sorrow.
B’ (8) Wherefore I beseech you that ye would confirm your love toward him.
A’ (9) For to this end also did I write, that I might know the proof of you, whether ye be obedient in all things. 10 To whom ye forgive any thing, I forgive also: for if I forgave any thing, to whom I forgave it, for your sakes forgave I it in the person of Christ; 11 Lest Satan should get an advantage of us: for we are not ignorant of his devices.
I have now extended this chiasm to include v3-11:
f: sorrow (v3)
e: my joy is the joy of you all (v3)
d: I wrote (v4)
c: love (v4)
b: overcharge (v5)
A: Sufficient to such a man is this punishment, which was inflicted of
many. (v6)
b: overmuch (v7)
c: love (v8)
d: did I write (v9)
e: to whom ye forgive anything, I also (v10)
f: lest satan should get the advantage of us (v11)
