Exegesis:
kai hupostrepsantes hoi apostoloi diēgēsanto autō hosa epoiēsan ‘and after returning the apostles told him all that they had done.’ kai connects v. 10 with v. 6. diēgeomai, cf. on 8.39.
apostolos ‘apostle,’ see on 6.13.
kai paralabōn autous hupechōrēsen kat’ idian ‘and taking them with him he withdrew privately.’ For hupochōreō cf. on 5.16.
paralambanō ‘to take along,’ ‘to take with.’
kat’ idian (also 10.23) ‘privately,’ ‘by oneself,’ including, of course, the disciples, as brought out e.g. in Brouwer, Nieuwe Vertaling, ‘alone with them.’
eis polin kaloumenēn Bēthsaïda ‘to, or, in the direction of a town called Bethsaida,’ preferably the latter, since Jesus did not go to, or, into Bethsaida (cf. v. 12 ‘in a lonely place’).
Translation:
On their return the apostles told him, or in co-ordination, ‘the apostles returned (or, came back to Jesus), and (then they) told him.’ Apostle, see on 6.13.
He took them (or, took them with him, as in New English Bible and others) and withdrew apart to indicates that Jesus, taking the apostles with him, left the crowd, and went with the apostles alone to Bethsaida; apart says explicitly what is implicit in the rest of the utterance. The items mentioned are variously expressed and distributed over the sentence in the versions, cf. e.g. ‘they were-told(-by-him) to accompany (him) on-their-own towards’ (Javanese), ‘the twelve disciples alone He took-with-him in leaving, and went to’ (Balinese), ‘he took them along (lit. carried them go) with him he pulled himself from amongst the people, he with the apostles alone went to’ (Sranan Tongo), ‘Jesus having called them, them alone, took them to’ (Tboli), ‘he led-them-away and separated-them-away to’ (Trukese, Pohnpeian).
City called Bethsaida, cf. on 1.26.
