Adam Clarke on Luke 16:20

There was a certain beggar named Lazarus - His name is mentioned, because his character was good, and his end glorious; and because it is the purpose of God that the righteous shall be had in everlasting remembrance. Lazarus, לעזר is a contraction of the word אלעזר Eliezar, which signifies the help or assistance of God - a name properly given to a man who was both poor and afflicted, and had no help but that which came from heaven.
