Robertson's Word Pictures (NT)
Every one that drinketh (pav o pinwn). Present active articular participle with pav, parallel to the indefinite relative with the second aorist active subjunctive (ov an pih) in verse John 4:14. 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").
