Here is John 17:19:

KAI hUPER AUTWN EGW AGIAZW EMAUTON,
hINA WSIN KAI AUTOI *HGIASMENOI* EN ALHQEIA.

("and for them do I sanctify myself, that they also
themselves may be sanctified in truth.")

Zerwick and Grosvenor has this note: "HGIASMENOI: (pf part pass) made (and kept
-- pf) holy for their God-given task".

Why does the perfect imply "and kept"?

And here is John 17:25:

PATER DIKAIE, KAI hO KOSMOS SE OUK EGNW

Zerwick and Grosvenor mention that "the force of the first KAI is not clear". Is
it clear to any of y'all?

Thanks!

Jonathan
