Philippians 3:2
Watch out for the "dogs!" [Note: "Dogs" were viewed with disgust by the ancient Jews (Deut. 23:18; II Kings 8:13; Rev. 22:15), so the term is used here derogatorily for Jewish Christians who were trying to impose on the church the requirements of the law of Moses]. Watch out for the evil workers! Watch out for those who mutilate the body meaninglessly! [Note: Paul here alludes, in a derogatory wordplay, to the Jewish practice of circumcision].
2 Peter 3:7
But, by means of the same word [of God], the present heavens and earth have been reserved for fire, awaiting the judgment and destruction [by God], along with [its] ungodly people.
Revelation 16:14-16
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 19:19-21
Then I saw the beast [See 13:1ff], and the kings of the earth and their armies assembled together to wage war against the One who was riding on the horse [i.e., Christ. See verse 11] and His army.
