Jesaja 18:4

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.

Whatever country it is that is meant here by "the land shadowing with wings," here is a woe denounced against it, for God has, upon his people's account, a quarrel with it. I. They threaten God's people (Isa 18:1, Isa 18:2). II. All the neighbours are hereupon called to take notice what will be the issue (Isa 18:3). III. Though God seem unconcerned in the distress of his people for a time, he will at length appear against their enemies and will remarkable cut them off (Isa 18:4-6). IV. This shall redound very much to the glory of God (Isa 18:7).

18:4 The Lord is untroubled by human activities; he watches quietly from his dwelling place and acts in his own time (see Ps 2:1-4).
