2 Thessalonians 2:1-3

BSB(i) 1 Now concerning the coming of our Lord Jesus Christ and our being gathered together to Him, we ask you, brothers, 2 not to be easily disconcerted or alarmed by any spirit or message or letter seeming to be from us, alleging that the Day of the Lord has already come. 3 Let no one deceive you in any way, for it will not come until the rebellion occurs and the man of lawlessness—the son of destruction—is revealed.
