Amos 8:11

In these verses is threatened, I. A general judgment of spiritual famine coming upon the whole land, a famine of the word of God, the failing of oracles and the scarcity of good preaching. This is spoken of as a thing at some distance: The days come, they will come hereafter, when another kind of darkness shall come upon that land of light. When Amos prophesied, and for a considerable time after, they had great plenty of prophets, abundant opportunities of hearing the word of God, in season and out of season; they had precept upon precept and line upon line; prophecy was their daily bread; and it is probable that they surfeited upon it, as Israel on the manna, and therefore God threatens that hereafter he will deprive them of this privilege. Probably in the land of Israel there were not so many prophets, about the time that their destruction came upon them, as there were in the land of Judah; and when the ten tribes went into captivity they saw not their signs, there were no more any prophets, none to show them how long, Psa 74:9. The Jewish church, after Malachi, had no prophets for many ages; and some think this threatening looks further yet, to the blindness which has in part happened to Israel in the days of the Messiah, and the veil that is on the heart of the unbelieving Jews.

famine of . . . hearing the words of the Lord--a just retribution on those who now will not hear the Lord's prophets, nay even try to drive them away, as Amaziah did (Amo 7:12); they shall look in vain, in their distress, for divine counsel, such as the prophets now offer (Eze 7:26; Mic 3:7). Compare as to the Jews' rejection of Messiah, and their consequent rejection by Him (Mat 21:43); and their desire for Messiah too late (Luk 17:22; Joh 7:34; Joh 8:21). So, the prodigal when he had sojourned awhile in the "far-off country, began to be in want" in the "mighty famine" which arose (Luk 15:14; compare Sa1 3:1; Sa1 7:2). It is remarkable that the Jews' religion is almost the only one that could be abolished against the will of the people themselves, on account of its being dependent on a particular place, namely, the temple. When that was destroyed, the Mosaic ritual, which could not exist without it, necessarily ceased. Providence designed it, that, as the law gave way to the Gospel, so all men should perceive it was so, in spite of the Jews' obstinate rejection of the Gospel.
