He will lift up a flag to [call] the distant nations [to bring His judgment on Judah],
And will whistle for them from the ends of the earth;
And indeed, they will come with great speed swiftly.

Ephraim's jealousy will end, and Judah's hostility will be eliminated. Ephraim will no longer be jealous of Judah, and Judah will no longer be hostile toward Ephraim.

The [mournful, inspired] oracle (a burden to be carried) concerning the Desert of the Sea (the seasonally flooded plains just south of Babylon):

As windstorms in the Negev (the South) sweep through,
So it (God’s judgment) comes from the desert, from [the hostile armies of] a terrifying land.

All you beasts of the field,
All you beasts (hostile nations) in the forest,
Come to eat.

For I will not be hostile forever or perpetually angry, for then man's spirit would grow faint before me, the life-giving breath I created.
