That's exactly what I wrote above... 😒 There is no bible scripture from that time period that has survived to this day as far as we know.

Edit: Okay I digress, he was likely quoting from a scripture in his letter but a Bible from that time period hasn't been discovered and perserved to this day.

The sole surviving work attributed to him is the Epistle of Polycarp to the Philippians, a mosaic of references to the Greek Scriptures, which, along with an account of The Martyrdom of Polycarp, forms part of the collection of writings called Apostolic Fathers. After the Acts of the Apostles, which describes the death of Stephen, the Martyrdom is considered one of the earliest genuine accounts of a Christian martyrdom.[2] Charles E. Hill argues extensively that the teachings Irenaeus ascribes to a certain apostolic "presbyter" throughout his writings represent lost teachings of Polycarp, his teacher.
