Passage
the Lord grant to him to find mercy from [the] Lord in that day and how much service he rendered in Ephesus *thou* knowest best.
the Lord grant to him to find mercy from [the] Lord in that day and how much service he rendered in Ephesus *thou* knowest best.
2 Timothy 1:16 The Lord grant mercy to the house of Onesiphorus, for he has often refreshed me, and has not been ashamed of my chain;
2 Timothy 1:17 but being in Rome sought me out very diligently, and found [me]
2 Timothy 1:18 the Lord grant to him to find mercy from [the] Lord in that day and how much service he rendered in Ephesus *thou* knowest best.
The verse centers on "mercy", "lord", "grant", "find", "much", "service", and "rendered". It is saying that the verse draws attention to "mercy" and "lord", so its meaning should be read from those terms before moving to application.
The prior verse says "but being in Rome sought me out...", giving immediate footing for "mercy" and "lord". In 2 Timothy context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "mercy" and "lord" with trust shaped by these words, not by a vague optimism outside the passage.
