(12) The questions require a negative answer, and show that the conduct of Israel is as inconsistent and senseless as the supposition involved in the interrogation: that horses should climb steep cliffs, or oxen plough in the rocky gorge. The conception of oppression, luxury, and pride being the forerunners of prosperity and peace is anomalous. The idea is, that that which should have insured the stability of the state, the embodiment of its conscience, had been turned into narcotic poison--the self-satisfaction of personal greed. Rosh, the Hebrew for "gall," is a poisonous kind of plant with bitter taste, and resembling, according to Jerome, stalks of grass, and propagating itself with such rapidity that it is difficult to exterminate it. (Comp. Hosea 10:4. Speaker's Commentary suggests "poppy-head.") In Amos 5:7 the word expressed here by "hemlock" is rendered "worm-wood," as in Jeremiah 9:15; Jeremiah 23:15; Deuteronomy 29:18, &c., a rendering which should have been retained here. Gall and worm-wood are constantly associated in Old Testament prophecy in this metaphorical sense.

Verses 12-14. - The prophet shows the folly of these evil doers who think in their own strength to defy judgment and to resist the enemy whom God is sending against them. Verse 12. - Shall horses run upon the rock? Can horses gallop safely over places covered with rocks and stones? Will one plough there with oxen? Do men plough the rock with their oxen? The answer, of course, is "No." Yet your conduct is equally foolish, your labour is equally lost. Some, dividing the words differently, translate, "Does one plough the sea with oxen?" which reminds one of the Latin proverb, "Litus arare bubus." Thus Ovid, 'Ep. Heroid,' 5:115 -

"Quid facis OEnone? Quid arenae semina mandas?
Non protecturis litora bubus aras." For ye have turned; or, that ye have turned. Judgment into gall (see note on Amos 5:7). Hemlock. Some plant with an acrid juice. Ye turn the administration of justice, which is "the fruit of righteousness," into the bitterest injustice and wrong. It were "more easy," says Pusey, "to change the course of nature or the use of things of nature, than the course of God's providence or the laws of his just retribution."

6:8-14 How dreadful, how miserable, is the case of those whose eternal ruin the Lord himself has sworn; for he can execute his purpose, and none can alter it! Those hearts are wretchedly hardened that will not be brought to mention God's name, and to worship him, when the hand of God is gone out against them, when sickness and death are in their families. Those that will not be tilled as fields, shall be abandoned as rocks. When our services of God are soured with sin, his providences will justly be made bitter to us. Men should take warning not to harden their hearts, for those who walk in pride, God will destroy.Shall horses run upon the rocks? or will one plough there with oxen?.... Will any man be so weak and foolish, to propose or attempt a race for horses upon rocks, where they and their riders would be in danger of breaking their necks? or would any man act so unwise a part, as to take a yoke of oxen to plough with them upon a rock, where no impression can be made? as vain and fruitless a thing it would be to attempt to bring such persons under a conviction of their sins, and to repentance for them, and reformation from them, who are given up to a judicial hardness of heart, like that of a rock, as are the persons described in the next clause; or as such methods with horses and oxen would be contrary to all the rules of reason and prudence, so as contrary a part do such persons act whose characters are next given, and there is no probability of bringing them to better sense and practice of things;

for ye have turned judgment into gall, and the fruit of righteousness into hemlock; that which would be beneficial to a nation, than which nothing is more so, as the exercise of justice, and judgment, into that which is bitter and pernicious to it, as injustice and oppression; see Amos 5:7.
