Verse 5. - For afore the harvest. God can rest thus tranquil, because he can step in at any time; and this he is about to do, before Assyria reaps her harvest. When the bud is perfect, etc.; rather, when the blossom is past, and the green grape is becoming a ripening bunch. He shall cut off (comp. Isaiah 10:33, 34). The metaphor is slightly varied in this place, to suit the imagery of the preceding clause, where Assyria has been represented as a vine-stock. Formerly her "boughs" were to be "lopped;" now her "branches" and "sprigs" or "sprouts" are to be cut away with pruning-hooks.

18:1-7 God's care for his people; and the increase of the church. - This chapter is one of the most obscure in Scripture, though more of it probably was understood by those for whose use it was first intended, than by us now. Swift messengers are sent by water to a nation marked by Providence, and measured out, trodden under foot. God's people are trampled on; but whoever thinks to swallow them up, finds they are cast down, yet not deserted, not destroyed. All the dwellers on earth must watch the motions of the Divine Providence, and wait upon the directions of the Divine will. God gives assurance to his prophet, and by him to be given to his people. Zion is his rest for ever, and he will look after it. He will suit to their case the comforts and refreshments he provides for them; they will be acceptable, because seasonable. He will reckon with his and their enemies; and as God's people are protected at all seasons of the year, so their enemies are exposed at all seasons. A tribute of praise should be brought to God from all this. What is offered to God, must be offered in the way he has appointed; and we may expect him to meet us where he records his name. Thus shall the nations of the earth be convinced that Jehovah is the God, and Israel is his people, and shall unite in presenting spiritual sacrifices to his glory. Happy are those who take warning by his judgment on others, and hasten to join him and his people. Whatever land or people may be intended, we are here taught not to think that God takes no care of his church, and has no respect to the affairs of men, because he permits the wicked to triumph for a season. He has wise reasons for so doing, which we cannot now understand, but which will appear at the great day of his coming, when he will bring every work into judgment, and reward every man according to his works.For afore the harvest,.... Or vintage: the above metaphor is carried on; before the designs and schemes of the people above described are ripe for execution, who promised themselves a large harvest of their neighbours:

when the bud is perfect; when the bud of the vine is become a perfect grape, though unripe; when the scheme was fully laid, and with perfect and consummate wisdom as imagined, though not brought into execution:

and the sour grape is ripening in the flower; things go on and promise well, as if the issue would be according to expectation, and there would be a good vintage. The sour grape may denote the temper and disposition of the above people against their enemies, their ill nature, and enmity to them; or the sins and transgressions, for which the judgment denounced came upon them:

he shall both cut off the sprigs with pruning hooks, and take away and cut down the branches; as the vinedresser; or rather as one that has no good will to the vine, cuts it with pruning hooks, not to make it better, but worse, and cuts off, not the dead withered and useless parts of it, but the sprigs that have buds and flowers, or unripe grapes, upon them, and even whole branches that have clusters on them, and takes them and casts them away, to be trodden under foot, or cast into the fire; so the Lord, or the king of Assyria, the instrument in the hand of God, should cut off the Ethiopians, or the Egyptians, with the sword, both small and great, when their enterprise should fail, and their promised success: or this is to be understood of the destruction of Sennacherib's army by the angel, when he was full of expectation of taking Jerusalem, and plundering that rich city. Jarchi and Kimchi interpret it of the destruction of the armies of Gog and Magog. The Targum is,

"and he shall kill the princes of the people with the sword, and their mighty ones he shall remove and cause to pass over.''
