Exegesis:

kai autoi exēgounto ‘and they on their part, or, in their turn, reported.’ autoi stresses the change of subject.

exēgeomai ‘to explain,’ here, ‘to report,’ ‘to tell.’

ta en tē hodō ‘the things on the road,’ i.e. ‘what had happened on the road,’ cf. on v. 32.

kai hōs egnōsthē autois tē klasei tou artou ‘and how he was recognized by them at the breaking of the bread,’ still dependent on exēgounto. hōs refers to the fact rather than to the mode. Here ginōskō is used in the meaning ‘to recognize.’ en tē klasei is temporal.

klasis ‘the (act of) breaking.’

Translation:
