The First Letter of clement to the Corinthians, section 5, reads: “. . . Let us place before our eyes the good Apostles. Peter, by unjust envy, underwent not one or two but many labours; and thus having borne testimony unto death he went unto the place of glory which was due to him. Through envy, Paul obtained the reward of patience. Seven times was he in bonds; he was scourged; was stoned. He preached both in the east and in the west, leaving behind him the glorious report of his faith. And thus, having taught the whole world righteousness, and reached the furthest extremity of the west, he suffered martyrdom, by the command of the governors, and departed out of this world, and went to the holy place, having become a most exemplary pattern of patience.”—Page 6 of A Translation of the Epistles of Clement of Rome, Polycarp and Ignatius, by Temple Chevallier, B.D., edition of 1833, London, England.
