2 Thessalonians 2:3-4 (New International Version)

³Don't let anyone deceive you in any way, for (that day will not come) until the rebellion occurs and the man of lawlessness^[a] is revealed, the man doomed to destruction. ⁴He will oppose and will exalt himself over everything that is called God or is worshiped, so that he sets himself up in God's temple, proclaiming himself to be God.
