Judah is the strong, resonant Old Testament name of the son of Jacob who was the ancestor of one of the tribes of Israel, and from whom the word Jew is derived. Some of the names' newfound popularity might be attributable to the similarly named Jude Law. Judah had risen more than seven hundred spots since 1998--so definitely one of the biblical boys' names moving up!
Judah Maccabee is acclaimed as one of the greatest warriors in Jewish history. In popular culture, Judah Ben-Hur was the eponymous hero of the novel and film, Ben-Hur, and, more recently, is borne by Judah Friedlander of 30 Rock, and is the name of the young son of Lucy Lawless.
