3 John 1:6-8

They have testified before the church of your love and friendship. You will do well to forward them on their journey [and you will please do so] in a way worthy of God's [service]. For these [traveling missionaries] have gone out for the Name's sake (for His sake) and are accepting nothing from the Gentiles (the heathen, the non-Israelites). So we ourselves ought to support such people [to welcome and provide for them], in order that we may be fellow workers in the Truth (the whole Gospel) and cooperate with its teachers.
