2 Timothy 1:18

It is immaterial whether we explain ὁ Κύριος, in this verse, of God the Father, the source of judgment, or of God the Son, the instrument of judgment. It is far-fetched to suppose that the repeated Κύριος … Κυρίου refer to different divine Persons. Huther's expl., followed by Alf., seems the best, that δῴη ὁ Κύριος had become so completely a formula that the recurrence did not seem harsh.

καὶ δσα κ. τ. λ.: This clause is an afterthought.

διηκόνησεν : The verb is used with a perfectly general reference here, as in Hebrews 6:10.

βέλτιον : The comparative here is intensive or elative. See Blass, Grammar, pp. 33, 141, 142. Other examples are in 1 Timothy 3:14 (Tisch.) and in the Received Text of 2 Timothy 1:17 of this chapter.
