John 4:14
That I shall give him (ou egw dwsw autw). Relative ou attracted to the case (genitive) of the antecedent (udatov). Future active indicative of didwmi.
Shall never thirst (ou mh diyhsei eiv ton aiona). The double negative ou mh is used with either the future indicative as here or the aorist subjunctive, the strongest possible negative. See both constructions (ou mh peinash and ou me diyhsei) in John 6:35. Jesus has not answered the woman's question save by the necessary implication here that he is superior to Jacob.
A well of water springing up unto eternal life (phgh udatov allomenou eiv zwhn aiwnion). "Spring (or fountain) of water leaping (bubbling up) unto life eternal." Present middle participle of allomai, old verb, in N.T. only here and Acts 3:8; Acts 14:10. The woman's curiosity is keenly excited about this new kind of water.
