John Gill Commentary 1 Timothy 3:14

"These things write I unto thee, hoping to come unto thee shortly;" — 1 Timothy 3:14 (ASV)

These things I write to you
Concerning the offices of bishops and deacons, their several qualifications, and the rules of judging of persons fit for such service:

hoping to come to you shortly ;
at Ephesus. He could not tell whether he could come or not, and therefore makes no promise, but hoped he should; and since it was uncertain, he thought fit to write the above things for his instruction and use.
