The saint resolved to climb Mount Qardu, traditionally believed to be the resting place of Noah's Ark, and recover a fragment of the ark upon hearing from the hermit Maroukeh that local people doubted the Great Flood.[10] Saint Jacob ascended the mountain and rested close to the summit; in his sleep, an angel placed a fragment of the ark close to him, and instructed him to awake.[10] The saint brought the relic to the hermit Maroukeh and, according to the saint's hagiography, a sacred spring appeared where the saint had rested, reputed to have healing properties.[10]
