Saint Zenas was the servant of Saint Zeno. They lived in the Arabian city of Philadelphia, and led a pious life. Saint Zeno possessed a large fortune, but he distributed his substance to the poor and manumitted slaves. Together with his devoted servant Zenas, he went to the governor and urged him to give up idolatry and accept Christ. They were tied to pillars, struck with iron hooks, and their wounds were rubbed with vinegar and salt.
Their sides and chests were scorched with fire, they were thrown in a pit, and boiling oil was poured over the sufferers. The saints endured all the tortures with forbearance and by the power of God they remained alive. Finally, the martyrs were beheaded with a sword in 304.
