Can anyone help me bible reference to the above?
There is no direct reference to the martyrdom of Peter or Paul in the Bible. However, John 21:18-19 predicts Peter's martyrdom and gives some indication of some of the circumstances. There is less for Paul, though he does anticipate his martyrdom in several places (e.g. 2Tim 4:6-8).
I would suggest looking at some Bible Encyclopedias for some of the traditions about these, some of which have early and reliable sources.
