Acts 4:26-28
The kings of the earth [i.e., Herod and Pilate] took their stand [against Jesus], and the rulers [of the Jews] gathered against the Lord and against His Anointed One [i.e., Christ].'
Revelation 16:14
For they are spirits of demons, which perform [supernatural] signs. These spirits go out to the kings of the whole world to assemble them for battle on the great day of Almighty God.
Revelation 20:8-9
and he will [again] go out to deceive the nations which are [located] throughout the whole world --- Gog and Magog. [Note: Based on Eze. 35-40, it appears that these names are used here figuratively for all the forces of wickedness which are enemies of God]. Satan will assemble them together for battle, and they will be as numberless as the sand on the seashore.
