Luke 22:31

Asked to have you (exhthsato). First aorist indirect middle indicative of exaitew, an old verb to beg something of one and (middle) for oneself. Only here in the N.T. The verb is used either in the good or the bad sense, but it does not mean here "obtained by asking" as margin in Revised Version has it. That he might sift you (tou siniasai). Genitive articular infinitive of purpose. First aorist active infinitive of siniazw, to shake a sieve, to sift, from sinion, a winnowing fan. Later word. Here only in the N.T.
