John 5:13

He that was healed (o iaqei). First aorist passive articular participle of iaomai (John's usual word). Who it was (ti estin). Present tense preserved in indirect question. Had conveyed himself away (exeneusen). First aorist active indicative of eknew, old verb to swim out, to slip out, or from ekneuw, to turn out, to turn the head to one side (to one side with which compare eneneuon, they nodded, Luke 1:62 ). Either of these verbs can explain the form here. The aorist tense simply states an antecedent action without being a pastperfect. A multitude being in the place (oclou onto en twi topwi). Genitive absolute and the reason for Christ's departure.
