"In the last letter that the apostle ever wrote, he speaks thus of this faithful disciple: “The Lord give mercy unto the house of Onesiphorus; for he oft refreshed me, and was not ashamed of my chain; but, when he was in Rome, he sought me out very diligently, and found me. The Lord grant unto him that he may find mercy of the Lord in that day.” 2 Timothy 1:16-18 . AA 491.1"
"The Lord give mercy unto the house of Onesiphorus; for he oft refreshed me, and was not ashamed of my chain: But, when he was in Rome, he sought me out very diligently, and found me. 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."
