And he will lift up an ensign {f} to the nations from afar, and will hiss to them from the end of the earth: and, behold, they shall come with speed swiftly:

(f) He will make the Babylonians come against them at his beck, and to fight under his standard.

Wesley's Notes

5:26 An ensign - To call them together for his service. From far - To the Chaldeans; for even Babylon is called a far country, chap.39:3. And he saith nations, because the Chaldean army was made up of several nations. Will hiss - Or, will whistle unto, or for them: will gather them together by his word. as shepherds gather their sheep. He intimates how easily and speedily God can do this work. From the ends - Which is not to be understood strictly, but with a latitude, from very remote places.

Jamieson-Fausset-Brown Bible Commentary

26. lift . ensign-to call together the hostile nations to execute His judgments on Judea (Isa 10:5-7; 45:1). But for mercy to it, in Isa 11:12; 18:3.

hiss-(Isa 7:18). Bees were drawn out of their hives by the sound of a flute, or hissing, or whistling (Zec 10:8). God will collect the nations round Judea like bees (De 1:44; Ps 118:12).

end of the earth-the widely distant subject races of which the Assyrian army was made up (Isa 22:6). The ulterior fulfilment took place in the siege under Roman Titus. Compare "end of the earth" (De 28:49, &c.). So the pronoun is singular in the Hebrew, for "them," "their," "whose" (him, his, &c.), Isa 5:26-29; referring to some particular nation and person [Horsley].

Matthew Henry's Concise Commentary

5:24-30 Let not any expect to live easily who live wickedly. Sin weakens the strength, the root of a people; it defaces the beauty, the blossoms of a people. When God's word is despised, and his law cast away, what can men expect but that God should utterly abandon them? When God comes forth in wrath, the hills tremble, fear seizes even great men. When God designs the ruin of a provoking people, he can find instruments to be employed in it, as he sent for the Chaldeans, and afterwards the Romans, to destroy the Jews. Those who would not hear the voice of God speaking by his prophets, shall hear the voice of their enemies roaring against them. Let the distressed look which way they will, all appears dismal. If God frowns upon us, how can any creature smile? Let us diligently seek the well-grounded assurance, that when all earthly helps and comforts shall fail, God himself will be the strength of our hearts, and our portion for ever.
