Robertson's Word Pictures (NT)
Grant mercy (dwh eleov). The phrase nowhere else in the N.T. Second aorist active optative of didwmi, the usual form being doih. This is the usual construction in a wish about the future.
Unto the house of Onesiphorus (tw Onhsiforou oikw). The same phrase in II Timothy 4:19. Apparently Onesiphorus is now dead as is implied by the wish in II Timothy 1:18.
For he oft refreshed me (oti pollakiv me aneyucen). First aorist active indicative of anayuxw, old verb, to cool again, in LXX and Koin‚ often, here only in N.T., but anayuciv in Acts 3:20. In the first imprisonment or the second. If he lost his life for coming to see Paul, it was probably recently during this imprisonment.
Was not ashamed of my chain (alusin mou ouk epaisxunqh). Passive deponent again (first aorist indicative) with accusative as in II Timothy 1:8. For alusin (chain) see Ephesians 6:20. Note absence of augment in epaisxunqh.
