Biblical character (Luke xvi:20), the poor man covered in sores; his name was extended in medieval usage to "any poor and visibly diseased person" (compare lazar, mid-14c., "one deformed and nauseous with filthy and pestilential diseases" [Johnson]). The name is from a Greek rendition of Hebrew El'azar, literally "God has helped."[Lazarus etymology, Lazarus origin, 英语词源]
