"41The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity; 42And shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth. 43Then shall the righteous shine forth as the sun in the kingdom of their Father. Who hath ears to hear, let him hear."

"20And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh. 21Then let them which are in Judaea flee to the mountains; and let them which are in the midst of it depart out; and let not them that are in the countries enter thereinto. 22For these be the days of vengeance, that all things which are written may be fulfilled. 23But woe unto them that are with child, and to them that give suck, in those days! for there shall be great distress in the land, and wrath upon this people. 24And they shall fall by the edge of the sword, and shall be led away captive into all nations: and Jerusalem shall be trodden down of the Gentiles, until the times of the Gentiles be fulfilled"
