From Joe Mullen
A v12 For if there be first a willing mind, it is accepted according to that a man hath, and not according to that he hath NOT (Gk. ou).
B v13 For I mean not that other men be eased, and ye burdened: v14 But by an EQUALITY,
C. that now at this time your ABUNDANCE may be a supply for their WANT,
C’. that their ABUNDANCE also may be a supply for your WANT:
B’ that there may be EQUALITY;
A’ v15 As it is written, He that had gathered much had nothing over; and he that had gathered little had NO (Gk. ou) lack.
