He declares: “[Jehovah] has raised up a signal to a great nation far away, and he has whistled to it at the extremity of the earth; and, look! in haste it will swiftly come in.”​—Isaiah 5:26; Deuteronomy 28:49; Jeremiah 5:15.

30. Who will rally “a great nation” against Jehovah’s people, and with what outcome?

³⁰ In ancient times a pole on an elevated site could serve as “a signal,” or rallying point, for people or armies. (Compare Isaiah 18:3; Jeremiah 51:27.) Now Jehovah himself will rally this unnamed “great nation” to execute his judgment.b He will ‘whistle to it,’ that is, draw its attention to his wayward people as an object worthy of conquest.
