As it is written, He that had gathered much had nothing over; and he that had gathered little had no lack. He that had gathered much, had nothing over - On the passage to which the apostle alludes, Exodus 16:18, I have stated that, probably, every man gathered as much manna as he could, and when he brought it home and measured it by the omer, (for this was the measure for each man's eating), if he had a surplus it went to the supply of some other family that had not been able to collect enough; the family being large, and the time in which the manna might be gathered, before the heat of the day, not being sufficient to collect a supply for so numerous a household; several of whom might be so confined as not to be able to collect for themselves. Thus there was an equality among the Israelites in reference to this thing; and in this light these words of St. Paul lead us to view the passage. To apply this to the present case: the Corinthians, in the course of God's providence, had gathered more than was absolutely necessary for their own support; by giving the surplus to the persecuted and impoverished Christian Jews these would be an equality; both would then possess the necessaries of life, though still the one might have more property than the other.
