26 And he will let a flag be lifted up as a sign to a far-off nation, whistling to them from the ends of the earth: and they will come quickly and suddenly. 27 There is no weariness among them, and no man is feeble-footed: they come without resting or sleeping, and the cord of their shoes is not broken. 28 Their arrows are sharp, and every bow is bent: the feet of their horses are like rock, and their wheels are like a rushing storm. 29 The sound of their armies will be like the voice of a lion, and their war-cry like the noise of young lions: with loud cries they will come down on their food and will take it away safely, and there will be no one to take it out of their hands.

Matthew Henry's Commentary on Isaiah 5:26-29

Commentary on Isaiah 5:24-30

(Read Isaiah 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.
