It is a familiar motif in Scripture. The Org. didn't pluck this one from thin air.
(1 Chronicles 16:31) . . .Let the heavens rejoice, and let the earth be joyful, And let them say among the nations, ‘Jehovah himself has become king!’
(Psalm 97:1, 2) . . .Jehovah himself has become king! Let the earth be joyful. Let the many islands rejoice. Clouds and thick gloom are all around him; Righteousness and judgment are the established place of his throne.
(Isaiah 24:23) . . .And the full moon has become abashed, and the glowing [sun] has become ashamed, for Jehovah of armies has become king in Mount Zion and in Jerusalem and in front of his elderly men with glory.
(Revelation 11:16-18) . . .And the twenty-four elders who were seated before God upon their thrones fell upon their faces and worshiped God, saying: “We thank you, Jehovah God, the Almighty, the One who is and who was, because you have taken your great power and begun ruling as king. But the nations became wrathful, and your own wrath came, and the appointed time for the dead to be judged, and to give [their] reward to your slaves the prophets and to the holy ones and to those fearing your name, the small and the great, and to bring to ruin those ruining the earth.”
The problem that I found with these texts is the phrase "has become". Is this phrase an addition of the NWT??
