'Us' in the Bible

and to give relief to you who are afflicted and to us as well when the Lord Jesus will be revealed from heaven with His mighty angels in flaming fire,

that you not be quickly shaken from your composure or be disturbed either by a spirit or a message or a letter as if from us, to the effect that the day of the Lord has come.

So then, brethren, stand firm and hold to the traditions which you were taught, whether by word of mouth or by letter from us.

Now may our Lord Jesus Christ Himself and God our Father, who has loved us and given us eternal comfort and good hope by grace,

Finally, brethren, pray for us that the word of the Lord will spread rapidly and be glorified, just as it did also with you;

Now we command you, brethren, in the name of our Lord Jesus Christ, that you keep away from every brother who leads an unruly life and not according to the tradition which you received from us.
