Like many humans who bore genes originating from the giant hominoids from the 12th Planet, King David was greatly admired for his strength and courage. That he took on one of these giants in the historic David and Goliath battle is not surprising, as he had a personal hatred of their domination, learned at his mothers knee. Female slaves, who were held in bondage to act as more than cooks and maids, became pregnant on occasion by the brutish and fiercely strong soldiers working in service to the mining outposts the 12th Planet rulers routinely put into place during every periodic passage of the 12th Planet through the Solar System. Chosen for their unhesitating brutality in the line of duty, these soldiers were used to keep the human slaves that worked the mines in line, and seldom displayed any tenderness, not even to their lovers.
Most often, a female slave that had been impregnated would die in childbirth, unable to deliver an oversized infant, taking her infant with her. On rare occasions half-breeds survived, often without their mothers who bled to death or were torn beyond repair. Davids mother, like he, bore genes from a half-breed, and thus had the hips to bear the product of rape and live. Beyond the great strength and unflinching courage which are traits of the giant hominoids from the 12th Planet, they have a singleness of purpose when aroused into anger. Thus he became a leader of the downtrodden, and was held in great esteem, this reverence expressed in devotion to his symbol, the Star of David. His lineage, the House of David, was noted primarily for its courageous leadership, not surprising when one considers the ancestry.
