“And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming:”
King James Version (KJV)
2:8 And then - When every prince and power that restrains is taken away. Will that wicked one - Emphatically so called, be revealed. Whom the Lord will soon consume with the spirit of his mouth - His immediate power. And destroy - With the very first appearance of his glory.
2Th 2:8 Then shall that Wicked be revealed. After the hindering power is removed. Whom the Lord shall consume. The Wicked power will be destroyed by the Lord's coming, and will continue to exist, possibly, until that event.
