3 John 1:6

They ¹  have testified to your love before the church. ²  You will do well to send them on their way in a manner worthy of God. ³ 

They have told the church about your love. You will do well to send them on their way in a manner worthy of God.

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.

They have told the church here of your friendship and your loving deeds. You do well to send them on their way in a manner that pleases God.

They've made a full report back to the church here, a message about your love. It's good work you're doing, helping these travelers on their way, hospitality worthy of God himself!

Who have given witness to the church of your love for them: and you will do well to send them on their way well cared for, as is right for servants of God:

they have testified to your love before the church. You will do well to send them on in a manner worthy of God;

who have borne witness of your love before the church. If you send them forward on their journey in a manner worthy of God, you will do well,

They ¹  have testified to your love before the church. ²  You will do well to send them on their way in a manner worthy of God. ³ 

¹ tn Grk “who” (a relative pronoun that continues the sentence begun in 3 John 5).

² sn Which church does the author refer to here? The church where Gaius is, the church where the author is, a different local church where the “brothers” are, or the ‘universal’ church, the church at large? Since the suggestion in 3 John 3 is that the “brothers” have come and testified in the author’s church about what Gaius has done for them, it seems most likely that the “church” mentioned here is also the author’s church, where he is currently located. Other possibilities cannot be ruled out, but seem unnecessarily complicated.

³ sn Now the author, after commending Gaius for his faithful service to the traveling missionaries in the past (see 3 John 5), now requests additional assistance at the present time (send them on their way in a manner worthy of God). Apparently the missionaries are on their way to visit the area where Gaius’ church is located a second time. They had been there once already and had returned with a good report of how Gaius had assisted them. It is entirely possible that they themselves carry with them the present letter as a letter of introduction. Along these lines it has been suggested that Demetrius (see 3 John 12) is one of these traveling missionaries, perhaps the leader of the delegation, and the author is formally introducing him to Gaius, since when he was there the last time he was a stranger (v. 5) but Gaius assisted him anyway.
