John 4:13

Every one that drinketh (pa o pinwn). Present active articular participle with pa, parallel to the indefinite relative with the second aorist active subjunctive (o an pih) in verse 3 John 14 . With this difference in the tenses used (pinwn, keep on drinking, pih, once for all). Note ek and the ablative both times, out of the water. Jesus pointed to the well ("this water").
