In vain have I struck your children, they have not received correction: your sword hath devoured your prophets, your generation is like a ravaging lion.

“"Some of those measures do not succeed," you say. Is a remedy, then, to be discontinued because the illness of some patients is incurable? You are looking at those who are so hardened that they are not affected by such correction. Concerning these it has been written: "In vain have I struck your children. They have not received correction."”

“Here he shows their hardness, because they are not corrected by scourges. And first he marvels at the excuse: why do you wish to contend with me in judgment? Job 9: if he should wish to contend with him, he could not answer him one for a thousand. Second, he shows their incorrigibility as regards the scourges of the lesser ones: in vain have I struck your sons; and of the greater ones: your sword devoured, by enemies, by your own deserts, sent unto slaughter, your prophets, false ones, namely Baal's, and the soothsayers: and as regards all in common: like a devastating lion, thus it lays waste; or, like a devastating lion, thus it is laid waste: for against a lion all rise up; so too against a wolf. Below, 6: in vain has the smelter smelted, for their malice has not been consumed. Call them reprobate silver, because the Lord has cast them off.”

“O generation, see ye the word of the Lord,.... Take notice of it, consider it; or, hear it, as the Septuagint, Syriac, and Arabic versions. Jarchi and Kimchi think (i) the pot of manna was brought out, and shown them, to be looked at by them, for the conviction of them, and confirmation of what follows: have I been a wilderness unto Israel? no: the Israelites were plentifully supplied by him when in the wilderness, and since they were brought into a land flowing with milk and honey; so that they stood in need of nothing; they had a constant supply of all good things: or a land of darkness? of misery, distress, and poverty; where no light of joy, comfort, and prosperity, is; a land that never sees the light, or enjoys the benefit of the sun, and so is barren and unfruitful; "a land of thorns", as the Septuagint version; or, "a desert and uncultivated land", as the Targum, and Syriac and Arabic versions. It may be rendered, "a land of the darkness of God" (k); that is, of the greatest darkness, of thick and gross darkness, alluding to that in Egypt; as the flame of God, and mountains of God, Sol 8:6, as Ben Melech and Kimchi observe: wherefore say my people, we are lords; and can reign without thee; or we have kings and princes, and have no need of thee, so Kimchi; but the word used seems to have another meaning, and to require another sense. The Targum is, "we are removed"; and the Vulgate Latin version, "we have gone back"; to which agrees the Jewish Midrash (l), mentioned by Jarchi, and confirmed with a passage out of the Misna (m), "we are separated from thee"; we have departed from thee, turned our backs on thee, have forsaken thee, and left thy ways and worship; and to do so was very ungrateful, when the Lord had so richly supplied them, that they had not lacked any good thing; and this sense agrees with what follows: we will come no more unto thee? some render it, "we have determined" (n); as having the same sense with the Arabic word, which signifies to "will" or determine anything; and then the meaning is, we are determined, we are resolved to come no more to thee, to attend thy worship and service any more; and so the Targum, "we will not return any more to thy worship.'' (i) So Mechilta apud Yalkut in loc. (k) "terra caliginis Dei", Gataker, Gussetius; "caliginis Jah", Montanus. (l) Midrash R. Tanchuma, apud Jarchi in loc. Vid. Yalkut Simeoni, in Ioc. (m) Misn. Trumot, c. 10. sect. 3. & Machshirin, c. 3. sect. 3. (n) "voluimus non veniemus", &c, De Dieu; "decrevimus non veniemus", Cocceius.”
