At this week's Watchtower study, paragraphs 11-13, it was discussed how lepers in Jesus' day were outcasts because leprosy was so contagious. Lepers were required to call out "leper, leper" as they walked so people would stay away from them.
The next paragraph says that according to rabbinical sources, a religious leader even threw rocks at a leper to keep him away. The next paragraph says that Jesus actually touched the leper man, showing him "dignity." and then healed him.
The paragraph says that shows how loving Jesus is.
Please understand that I am not saying that Jesus is not loving, but I believe that there is another way to look at this Bible passage.
I think that the reason the people didn't want the lepers to be near them was because they knew it would spread to them. They weren't bad people and the religious leaders were not bad or heartless. They just did not want to catch leprosy.
Jesus didn't have to worry about catching the disease because he wouldn't be adversely affected.
Of course Jesus could touch the man.
