3 John 1:5-8

Beloved, you are acting faithfully in whatever you accomplish for the brethren, and especially when they are strangers; and they have testified to your love before the church. You will do well to send them on their way in a manner worthy of God. For they went out for the sake of the Name, accepting nothing from the Gentiles. Therefore we ought to support such men, so that we may be fellow workers with the truth.
