There are no OT prophecies about Timothy

Paul says in 1 Tim.1:18, "This charge I commit unto thee, son Timothy, according to the prophecies which went before on thee." Unfortunately, there are no Old Testament prophecies pertaining to, or referring to, Timothy.
C Dennis McKinsey, EBE, p398.

There are no OT prophecies about Timothy. However Mr McKinsey has forgotten that there is the NT office of prophet.

(1 Cor 12:28 NIV) And in the church God has appointed first of all apostles, second prophets, third teachers, then workers of miracles, also those having gifts of healing, those able to help others, those with gifts of administration, and those speaking in different kinds of tongues.

(Eph 4:11-12 NIV) It was he who gave some to be apostles, some to be prophets, some to be evangelists, and some to be pastors and teachers, {12} to prepare God's people for works of service, so that the body of Christ may be built up

Later Paul in the same letter refers to a specific time in Timothy's life when he was given a prophetic message when the body of elders laid their hands on him.

(1 Tim 4:14 NIV) Do not neglect your gift, which was given you through a prophetic message when the body of elders laid their hands on you.
