3 John 1:5-8

5Beloved, thou doest a faithful work in whatsoever thou doest toward them that are brethren and strangers withal; 6who bare witness to thy love before the church: whom thou wilt do well to set forward on their journey worthily of God: 7because that for the sake of the Name they went forth, taking nothing of the Gentiles. 8We therefore ought to welcome such, that we may be fellow-workers for the truth.
