“Know ye that our brother Timothy is set at liberty; with whom, if he come shortly, I will see you.”
King James Version (KJV)
13:23 If he come - To me.
Heb 13:23 [Our] brother Timothy is set at liberty. How intimately Timothy was associated with Paul all his epistles show. Timothy too joined him at Rome during his imprisonment. (See salutations of the so-called "Prison Epistles", Php 1:1 Col 1:1 Phm 1:1.) This language implies that Timothy had been arrested and afterwards set free. Of this imprisonment, or just where it occurred, there is no other history.
