Преподобни Йоан Вехтопещерник е живял през VІІІ век. Той се подвизавал в манастира, основан в Палестина близо до Йерусалим от св. Харитон Изповедник. За храм на манастира служела една пещера. По-късно св. Харитон живял и в друга пещера близо до гр. Йерихон, където също построил манастир. Затова първата пещера била наречена Вехта (стара), откъдето и преподобни Йоан бил наречен Вехтопещерник. Обикнал Христа от цялото си сърце, той още от младини започнал да пътува по светите места и да слуша съвети от святи люде и отшелници. Най-после се настанил в Харитоновата пещер, където се отдал на строги подвизи. Много години прекарал в пост, молитва и бдение, като винаги мислел за смъртта и се учел на смирение. Достигнал святост и тихо завършил живота си.
Hieromartyr Paphnutius of Jerusalem was a bishop. He underwent many sufferings from the pagans and was tortured by fire, wild beasts, and finally was beheaded by the sword.
Some suggest that the hieromartyr Paphnutius was an Egyptian bishop and suffered together with many other Egyptians, exiled to the Palestinian mines during the persecution by Diocletian (284-305).
The myrrh-streaming relics of the hieromartyr were glorified by miracles. The Canon in his honor was composed during the Iconoclast period (before 842). In the final Ode is a petition for the hieromartyr to put an end to the heresy disrupting the Church.
Saint John of the Ancient Caves is so called because he lived during the eighth century in the Lavra of St Chariton (September 28). This was called the "Old," or ancient cave, since it was one the oldest of the Palestinian monasteries. The Lavra was situated not far from Bethlehem, near the Dead Sea.
St John in his early years left the world, went to venerate the holy places of Jerusalem, and settled at the Lavra, where he labored in fasting, vigil, and prayer. He was ordained to the holy priesthood, and glorified by his ascetic life.
