Babylonish garment
A Babylonish garment was a richly embroidered or woven robe produced at Babylon and prized throughout the ancient world for its elaborate ornamentation. Babylon was renowned in antiquity for its luxury textile industry, producing garments of exceptional quality and color that were traded across the Near East. Such a garment was among the items Achan confessed to hiding when he violated the ban (herem) on the spoils of Jericho: I saw among the spoils a goodly Babylonish garment, and two hundred shekels of silver, and a wedge of gold (Joshua 7:21).
The episode of Achan's sin explains Israel's surprising defeat at Ai after the miraculous victory at Jericho. Achan's covetousness — triggered by the sight of a beautiful foreign garment — illustrates the danger of what the eye sees and the hand desires in violation of divine command. The garment's Babylonian origin made it emblematic of the tempting luxury of foreign culture, the same cultural seduction the prophets would later warn against as Israel encountered greater wealth and power in the nations surrounding her.
