Martyrdom
The surviving tradition presents Jacob's death as the climax of a sustained effort to make him apostatize. Dragged from the monastery on Mount Hamatoura, he was brought down to Tripoli and delivered to the wali, who subjected him to a long ordeal of pressure and torment. According to these accounts he was steadfast under both flattery and violence, and after about a year was put to death by beheading on October 13.
The burning of his body afterward is consistently reported as a deliberate act to deprive the Christian community of his relics and of a martyr's burial. The recovery of relics associated with him—commemorated by a second observance on July 3 marking their discovery in 2008—later became part of his veneration at Hamatoura.
