Exegesis:

kai eiselthōn diērcheto tēn Ierichō ‘and after entering Jericho he passed through it.’ diērcheto is durative imperfect. The verse sets the scene for the subsequent events. For dierchomai cf. on 2.15.

Translation:

Was passing through, or, ‘made his way through it,’ ‘passed in the midst of the town’ (Tae’), implying that Jesus did not stay in the city but entered it only to leave it at the other end.
