'Us' in the Bible

and to you who are being afflicted, rest with us at the revelation of the Lord Jesus from heaven with his powerful angels,

that you not be easily shaken from your composure, nor be troubled either by a spirit or by a message or by a letter {alleged to be from us}, to the effect that the day of the Lord has arrived.

So then, brothers, stand firm and hold fast to the traditions which you were taught, whether by [spoken] word or by letter from us.

Now may our Lord Jesus Christ himself and God our Father, who has loved us and given [us] eternal encouragement and good hope by grace,

Finally, brothers, pray for us, that the word of the Lord may progress and be honored, just as also [it was] with you,

But we command you, brothers, in the name of our Lord Jesus Christ, [that] you keep away from every brother who lives irresponsibly and not according to the tradition that they received from us.

For you yourselves know how it is necessary to imitate us, that we did not behave irresponsibly among you,

not that we do not have the right, but so that we may give ourselves [as] an example to you, so that [you] may imitate us.
