Keil & Delitzsch CommentaryIsaiah 18

Read Isaiah 18 in the BibleIsaiah 18:4-6
Isa 18:4-6 The prophet knows for certain that the messengers may be home and announce this act of Jehovah to their own people and to all the world. “For thus hath Jehovah spoken to me: I will be still, and will observe upon my throne during clear weather in sunshine, during a cloud of dew in the heat of harvest. For before the harvest, when the blossom falls off, and the fruit becomes the ripening grape: then will He cut off the branches with pruning-hooks; and the tendrils He removes, breaks off. They are left altogether to the birds of prey on the mountains, and to the cattle of the land; and the birds of prey summer thereon, and all the cattle of the land will winter thereon.” The prophecy explains itself here, as is very frequently the case, especially with Isaiah; for the literal words of v. 6 show us unquestionably what it is that Jehovah will allow to develop itself so prosperously under favourable circumstances, and without any interposition on His part, until He suddenly and violently puts an end to the whole, must as it is approaching perfect maturity. It is the might of Assyria. Jehovah quietly looks on from the heavenly seat of His glorious presence, without disturbing the course of the thing intended. This quietness, however, is not negligence, but, as the hortative expressions show, a well-considered resolution. The two Caphs in v. 4 are not comparative, but indicate the time. He remains quiet whilst there is clear weather with sunshine (עלי indicating continuance, as in Jer 8:18; 1Sa 14:32), and whilst there is a dew-cloud in the midst of that warmth, which is so favourable for the harvest, by causing the plants that have been thoroughly heated in the day and refreshed at night by the dew, to shoot up and ripen with rapidity and luxuriance. The plant thought of, as v. 5 clearly shows, is the vine. By liphnē kâtzir (before the harvest) we are either to understand the period just before the wheat-harvest, which coincides with the flowering of the grape; or, since Isaiah uses kâtzir for bâzri in Isa 16:9, the time at the close of the summer, immediately preceding the vintage. Here again the Caph indicates the time. When the blossoming is over, so that the flower fades away, and the fruit that has set becomes a ripening grape (boser, as in Job 15:33, not in the sense of labruscum, but of omphax; and gâmal, maturescere, as in Num 17:8, maturare), He cuts off the branches (zalzalilm, from zilzēl, to swing to and fro; compare the Arabic dâliye, a vine-branch, from dalâ, to hang long and loose) upon which the nearly ripened grapes are hanging, and removes or nips off (התז = התז with a pausal sharpening of the tzere, which is lengthened by the tone, from tâzaz or tı̄z in post-biblical Hebrew, to knock off, knock to pieces, or weaken (compare tâshash). On this change of vowels in pause, see at Gen 17:14; and compare Olshausen, §91, d. For an example of the post-biblical use of the word, vid., b. Sanhedrin 102 a, “like two sticks hammattı̄zōth,” i.e., one of which “hits the other in two” (hittiz, apparently from tūz, or tiz, like hinnı̄ach from nuach).) the tendrils (netishoth, as in Jer 5:10, from nâtash, to stretch far out; niphal, to twist about a long way, Isa 16:8, compare Jer 48:32); an intentional asyndeton with a pictorial sound. The words of Jehovah concerning Himself have here passed imperceptibly into words of the prophet concerning Jehovah. The ripening grapes, as Isa 18:6 now explains, are the Assyrians, who were not far from the summit of their power; the fruit-branches that are cut off and nipped in pieces are their corpses, which are now through both summer and winter the food of swarms of summer birds, as well as of beasts of prey that remain the whole winter through. This is the act of divine judgment, to which the approaching exaltation of the banner, and the approaching blast of trumpets, is to call the attention of the people of Ethiopia.
Isaiah 18:7
Isa 18:7 What effect this act of Jehovah would have upon the Ethiopian kingdom, if it should now take place, is described in Isa 18:7 : “At that time will there be offered as a homage to Jehovah of hosts a nation stretched out and polished, and from a terrible people, far away on the other side; a nation of command upon command and treading down, whose land rivers cut through, at the place of the name of Jehovah of hosts, the mountain of Zion.” עם (a people), at the commencement, cannot possibly be equivalent to מעם (from a people). If it were taken in this sense, it would be necessary to make the correction accordingly, as Knobel has done; but the important parallels in Isa 66:20 and Zep 3:10 are against this. Consequently ‛am and goi (people and nation) must be rendered as subjects; and the מן in מעם must be taken as partitive. Ethiopia is offered, i.e., offers itself, as a free-will offering to Jehovah, impelled irresistibly by the force of the impression made by the mighty act of Jehovah, or, as it is expressed in “the Titan among the Psalms” (Psa 68:32, probably a Davidic psalm of the time of Hezekiah), “there come kingdoms of splendour out of Egypt; Cush rapidly stretches out its hands to Elohim.” In order that the greatness of this spiritual conquest might be fully appreciated, the description of this strangely glorious people is repeated here; and with this poetical rounding, the prophecy itself, which was placed as a kind of overture before the following massa Mitzraim when the prophet collected the whole of his prophecies together, is brought to a close. The Oracle Concerning Egypt - Isaiah 19 The three prophecies in Isa 18:1-7, 19 and Isa 20:1-6 really form a trilogy. The first (Isa 18:1-7), which, like chapter 1, the introduction to the whole, is without any special heading, treats in language of the sublimest pathos of Ethiopia. The second (chapter 19) treats in a calmer and more descriptive tone of Egypt. The third (Isa 20:1-6) treats of both Egypt and Ethiopia in the style of historic prose. The kingdom to which all three prophecies refer is one and the same, viz., the Egypto-Ethiopian kingdom; but whilst Isa 18:1-7 refers to the ruling nation, chapter 19 treats of the conquered one, and Isa 20:1-6 embraces both together. The reason why such particular attention is given to Egypt in the prophecy, is that no nation on earth was so mixed up with the history of the kingdom of God, from the patriarchal times downwards, as Egypt was. And because Israel, as the law plainly enjoined upon it, was never to forget that it had been sheltered for a long time in Egypt, and there had grown into a great nation, and had received many benefits; whenever prophecy has to speak concerning Egypt, it is quite as earnest in its promises as it is in its threats. And thus the massa of Isaiah falls into two distinct halves, viz., a threatening one (Isa 19:1-15), and a promising one (Isa 19:18-25); whilst between the judgment and the salvation (in Isa 19:16 and Isa 19:17) there stands the alarm, forming as it were a connecting bridge between the two. And just in proportion as the coil of punishments is unfolded on the one hand by the prophet, the promise is also unfolded in just as many stages on the other; and moving on in ever new grooves, rises at length to such a height, that it breaks not only through the limits of contemporaneous history, but even through those of the Old Testament itself, and speaks in the spiritual language of the world-embracing love of the New Testament.
