Exegesis:

kai poreuomenōn autōn en tē hodō ‘and as they were going along the road.’ Subject is Jesus and his disciples, as in v. 56. poreuomenōn is best understood as a continuation of poreuesthai, in v. 51, since from that verse on till 19.27 Luke’s theme is that of Jesus’ journey from Galilee to Jerusalem (see commentaries, especially Grundmann).

akolouthēsō soi hopou ean aperchē ‘I will follow you wherever you go.’ For akoloutheō cf. on 5.11.

aperchomai here ‘to go’ with the implication of going to some place (cf. 17.23). Elsewhere usually ‘to go away,’ ‘to go back.’

Translation:

As they were going along the road, or, “as they went on their way” (Good News Translation), ‘as they were travelling on,’ ‘on their journey’ (Tae’).

Him, i.e. Jesus, who is referred to by his proper name in the next verse; this order may have to be reversed or otherwise adjusted.

Wherever you go may have to be translated, ‘on all journeys you make,’ ‘to all places that you go to.’
