(21) A noble vine.--Literally, a Sorek vine. Elsewhere rendered choice or choicest (Genesis 49:11; Isaiah 5:2). The word "Sorek" points primarily to the dark purple of the grape, and then to the valley of Sorek, between Ascalon and Gaza (Judges 16:4).

Wholly a right seed.--Literally, a seed of truth, parallel with the "good seed" in the Parable of the Tares. Here, however, as in Isaiah 5:1-7, which Jeremiah seems to have in his mind, stress is laid not on the mingling of the evil with the good, but on the degeneration which had changed the character of that which God had planted.

Art thou turned . . .?--Better, hast thou changed thyself . . .?

Plant.--Better, branches.

Verse 21. - A noble vine. Jeremiah means the choicest kind of Oriental vine, called sorek (from the dark-red color of its grapes), and mentioned again in Isaiah 5:2. The figure of the vine is one endeared to us by its association especially with our Lord; it was endeared to the Jews by the annual festivities of the vintage. The sacred writers are never afraid of its palling on the ear by repetition (comp. Jeremiah 5:10; Jeremiah 6:9; Jeremiah 12:10; Isaiah 5:1-7; Isaiah 27:2, 3; Ezekiel 17:6; Psalm 80:8-16). A right seed; i.e. a vine-shoot of the genuine sort. "Seed" for "shoot," as in Isaiah 17:11 (scrap. ver. 10). The degenerate plant; rather, degenerate shoots (if at least the text is right).

2:20-28 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.Yet 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.''
