He that withholdeth corn - Who refuses to sell because he hopes for a dearth, and then he can make his own price.
The people shall curse him - Yes, and God shall curse him also; and if he do not return and repent, he will get God's curse, and the curse of the poor, which will be a canker in his money during time, and in his soul throughout eternity.
In the early stages of commerce there seems no way of making money rapidly so sure as that of buying up grain in time of famine, waiting until the dearth presses heavily, and then selling at famine prices. Men hate this selfishness, and pour blessings upon him who sells at a moderate profit.
