Isaiah 18:3

3 Look when someone raises a flag on the mountains. Listen when someone blows a ram's horn, all you inhabitants of the world who live on the earth.

Isaiah 18:3 Meaning and Commentary

Isaiah 18:3

All ye inhabitants of the world, and dwellers on the earth,
&c.] All the men of the world are here called upon, either by the Lord, or rather by the prophet, to be eye and ear witnesses of the judgment that should be inflicted upon the above nation, and of the salvation of his own people; which should be so manifest, that all should see it as easily as an ensign set up on a mountain; and the news of it should ring through the earth, and be as plainly heard as when a trumpet is blown: unless it should be thought that these are the words of the messengers sent to the above nation, addressing them in such terms, assuring them, that, however stupid and secure they were now, they should quickly see the sign and hear the alarm of war; it being usual to call any large kingdom the world, and the earth: see ye, when be lifteth up an ensign on the mountains;
or ye shall see this as clearly as when a flag is set up on a mountain; or ye shall be sensible of this judgment coming on, when a standard shall be set up on the mountains, to gather the people to war. Vitringa interprets this of the mountains of Judea, where the Assyrians would set up their banners, and blow their trumpets, as follows: and when he bloweth a trumpet, hear ye;
or, "ye shall hear"; the trumpet sounding as an alarm of war, by which the people will be summoned, and come to execute the judgment threatened. The Targum is,

``ye shall hear the redemption;''

that is, of Israel, in the times of the Messiah, and in the war of Gog and Magog; of which times Jarchi and Kimchi interpret this whole prophecy.

Isaiah 18:3 In-Context

1 How horrible it will be for the land of whirring wings which lies beyond the rivers of Sudan.

2 It sends messengers by sea in boats made of reeds [skimming] over the surface of the water. Go, swift messengers, to a tall and smooth-skinned people, a people [who are] feared far and near, a strong and aggressive nation, whose land is divided by rivers.

3 Look when someone raises a flag on the mountains. Listen when someone blows a ram's horn, all you inhabitants of the world who live on the earth.

4 This is what the LORD says to me: I will keep quiet and watch from my dwelling place. My presence will be like scorching heat in the sunshine, like heavy dew in the heat of the harvest.

5 Before the harvest, when blossoms are gone and grapes are ripening from blossoms, he will cut off the shoots with pruning shears and chop off the spreading branches.
