2 Thessalonians 2:3-4

Living_Oracles(i) 3 Let no one lead you into a mistake by any means; because the apostasy must first appear, and the man of sin, the son of perdition, must be first revealed, 4 who opposes and exalts himself against every one called a god, or an object of worship; so that he places himself in the temple of God, openly exhibiting himself, that he is a god.
