Robertson's Word Pictures (NT)
Remember (mnhmoneue). "Keep in mind," as in Revelation 2:5.
Therefore (oun). Resumptive and coordinating as in Revelation 1:19; Revelation 2:5.
Thou hast received (eilhfav). Perfect active indicative of lambanw, "as a permanent deposit" (Vincent).
Didst hear (hkousav). First aorist active indicative, the act of hearing at the time.
And keep it (kai threi). Present active imperative of threw, "hold on to what thou hast."
And repent (kai metanohson). First aorist active imperative of metanoew, "Turn at once."
If therefore thou shalt not watch (ean oun mh grhgorhshv). Condition of third class with ean mh and the first aorist (ingressive) active subjunctive of grhgorew, "if then thou do not wake up."
I will come (hcw). Certainly future active here, though probably aorist subjunctive in Revelation 2:25.
As a thief (wv klepthv). As Jesus had already said (Matthew 24:43; Luke 12:39), as Paul had said (I Thessalonians 5:2), as Peter had said (II Peter 3:10), as Jesus will say again (Revelation 16:15).
Thou shalt not know (ou mh gnwv). Strong double negative ou mh with second aorist active subjunctive of ginwskw, though some MSS. have the future middle indicative gnwsh.
What hour (poian wran). A rare classical idiom (accusative) surviving in the Koin‚ rather than the genitive of time, somewhat like John 4:52; Acts 20:16 (Robertson, Grammar, p. 470f.). Indirect question with poian.
