6:9-16 God, having showed how necessary it was that they should do justly, here shows how plain it was that they had done unjustly. This voice of the Lord says to all, Hear the rod when it is coming, before you see it, and feel it. Hear the rod when it is come, and you are sensible of the smart; hear what counsels, what cautions it speaks. The voice of God is to be heard in the rod of God. Those who are dishonest in their dealings shall never be reckoned pure, whatever shows of devotion they may make. What is got by fraud and oppression, cannot be kept or enjoyed with satisfaction. What we hold closest we commonly lose soonest. Sin is a root of bitterness, soon planted, but not soon plucked up again. Their being the people of God in name and profession, while they kept themselves in his love, was an honour to them; but now, being backsliders, their having been once the people of God turns to their reproach.
15. sow … not reap—fulfilling the threat (Le 26:16; De 28:38-40; Am 5:11).
