“The Lord grant unto him that he may find mercy of the Lord in that day: and in how many things he ministered unto me at Ephesus, thou knowest very well.”
King James Version (KJV)
2Ti 1:18 In that day. The day when he shall be called to meet the Lord. He ministered unto me at Ephesus. He then belonged to Ephesus, had ministered to Paul there, and shown his faithfulness again at Rome. The language seems to imply that these kind deeds were past. Perhaps Onesiphorus had started back home.
