Who was Lazarus?
While Rainsford and General Zaroff are having dinner and discussing the "hunt," General Zaroff tells Rainsford about one of his former prey. He says to avoid "Death Swamp" because one other fellow ran into it and it was full of quicksand. "The deplorable part of it was Lazarus followed him. I loved Lazarus he was the finest hound in my pack."
As far as the Biblical sense, John 11:1-46, "In verse 3 we see that Mary and Martha know Jesus loves Lazarus. Then in verse 5 John points out again that Jesus loved Martha, Mary and Lazarus. Why the repetition? Obviously, John wants to emphasize the love between Jesus and this family. Perhaps the reason for the repetition is that Jesus is about to do something that doesn’t seem very loving. He’s going to let Lazarus die. Maybe John is just trying to emphasize that just because bad things happen to us, it doesn’t mean God doesn’t love us. Later on in the account, we see Jesus “deeply moved” and “troubled” and even weeping. So there should be no question that Jesus cares. Jesus could have healed or raised Lazarus from a distance, but perhaps he wants to go to Bethany to test the disciples willingness to follow Him into danger."
Maybe this refers to Lazarus was being put to the test of his willingness to put himself in danger for his master, General Zaroff.
