John 4:50

'''λέγει αὐτῷ ὁ Ἰησοῦς· πορεύου, ὁ υἱός σου ζῇ. Ἐπίστευσεν ὁ ἄνθρωπος τῷ λόγῳ ὃν εἶπεν αὐτῷ ὁ Ἰησοῦς καὶ ἐπορεύετο'''

Jesus said to him go, your son lives. The man believed the words Jesus said to him and went on his way.


 * Use of the historical present here, for example λέγει.
 * On the other hand, some other verbs are aorist: Ἐπίστευσεν and εἶπεν.
 * πορεύου - from πορεύομαι. This is 2nd person sg. middle imperative. 2nd person sg imperatives are typically irregular but this one follows the λύου pattern.
 * ἐπορεύετο also from πορεύομαι. This is the imperfect middle 3P sg. Imperfect is used to describe a progressive action. One of the functions is to set the scene for ("lay the carpet for") various events. This can be seen in the next verse where the man (the ruler) is on his way and then his servants meet him during the trip.
