| Barnes' Notes on the Bible A noble vine - Properly, a Sorek vine (see Isaiah 5:2), which produced a red wine Proverbs 23:31, and had a lasting reputation Genesis 49:11. A right seed - literally, "a seed of truth," i. e., true, genuine seed, not mixed with weeds, nor with seed of an inferior quality. Compare Matthew 13:24. How then art thou turned - Or, "How then" hast thou changed thyself "unto me" (i. e., to my hurt or vexation) "into the degenerate" branches "of a strange vine?" The stock, which was God's planting, was genuine, and of the noblest sort: the wonder was how such a stock could produce shoots of a totally different kind Deuteronomy 32:32.
Clarke's Commentary on the BibleI had planted thee a noble vine - I gave thee the fullest instruction, the purest ordinances, the highest privileges; and reason would that I should expect thee to live suitably to such advantages; but instead of this thou art become degenerate; the tree is deteriorated, and the fruit is bad. Instead of being true worshippers, and of a holy life and conversation, ye are become idolaters of the most corrupt and profligate kind. See Isaiah 5:1, etc., where the same image is used.
Gill's Exposition of the Entire BibleYet I had planted thee a noble vine, wholly a right seed,.... It is usual to compare the people of the Jews to a vineyard, and to vines; and their settlement in the land of Canaan to the planting of vines in a vineyard; see Isaiah 5:1. Kimchi says this is spoken concerning Abraham; no doubt respect is had to the Jewish fathers, such as Abraham, Isaac, and Jacob, the twelve patriarchs, Moses, Joshua, and Caleb, and the like; who, having the true and right seed of grace in them, became like choice and noble vines, and brought forth much fruit, and were deserving of imitation by their posterity: how then art thou turned into the degenerate plant of a strange vine unto me? like a vine that grows in the woods, and brings forth wild grapes; so these, their sons, degenerating in practice from their fathers, became corrupt in themselves, and unprofitable to God. The Targum of the whole is, "I set you before me as the plant of a choice vine, all of you doing truth; but how are you changed before me in your corrupt works? ye have declined from my worship, ye are become as a vine in which there is no profit.''
Keil and Delitzsch Biblical Commentary on the Old TestamentIn this whoring with the false gods, Israel shows its utter corruption. I have planted thee a noble vine; not, with noble vines, as we translate in Isaiah 5:2, where Israel is compared to a vineyard. Here Israel is compared to the vine itself, a vine which Jahveh has planted; cf. Psalm 80:9; Hosea 10:1. This vine was all (כּלּה, in its entirety, referred to שׂורק, as collect.) genuine seed; a proper shoot which could bear good grapes (cf. Ezekiel 17:5); children of Abraham, as they are described in Genesis 18:19. But how has this Israel changed itself to me (לי, dativ. incommodi) into bastards! סוּרי is accus., dependent on נהפכתּ; for this constr. cf. Leviticus 13:25; Psalm 114:8. סוּרים sig. not shoots or twigs, but degenerate sprouts or suckers. The article in הגּפן is generic: wild shoots of the species of the wild vine; but this is not the first determining word; cf. for this exposition of the article Jeremiah 13:4; 2 Samuel 12:30, etc., Ew. 290, a3); and for the omission of the article with נכריּה, cf. Ew. 293, a. Thus are removed the grammatical difficulties that led Hitz. to take ' סוּרי וגוquite unnaturally as vocative, and Graf to alter the text. "A strange vine" is an interloping vine, not of the true, genuine stock planted by Jahveh (Jeremiah 2:10), and which bears poisonous berries of gall. Deuteronomy 32:32.

Jamieson-Fausset-Brown Bible Commentary21. The same image as in De 32:32; Ps 80:8, 9; Isa 5:1, &c. unto me-with respect to Me.
Matthew Henry's Concise Commentary2:20-28 Notwithstanding all their advantages, Israel had become like the wild vine that bears poisonous fruit. Men are often as much under the power of their unbridled desires and their sinful lusts, as the brute beasts. But the Lord here warns them not to weary themselves in pursuits which could only bring distress and misery. As we must not despair of the mercy of God, but believe that to be sufficient for the pardon of our sins, so neither must we despair of the grace of God, but believe that it is able to subdue our corruptions, though ever so strong. |
