Opening their treasures (anoixante tou qhsaurou autwn). Here "treasures" means "caskets" from the verb (tiqhmi), receptacle for valuables. In the ancient writers it meant "treasury" as in 1Macc. 3:29. So a "storehouse" as in Matthew 13:52 . Then it means the things laid up in store, treasure in heaven ( Matthew 6:20 ), in Christ ( Colossians 2:3 ). In their "caskets" the Magi had gold, frankincense, and myrrh, all found at that time in Arabia, though gold was found in Babylon and elsewhere.
