Yes and what was the moral of the Ten Lepers? "One of them, when he saw he was healed, came back, praising God in a loud voice. He threw himself at Jesus' feet and thanked him - and he was a Samaritan.."
Jesus asked:
"Were not all ten cleansed? Where are the other nine? Was no one found to return and give praise to God except this foreigner?"
Then he said to him:
"Rise and go; your faith has saved you." Luke 17:11-19.
This last line is significant. We do not know what eventually happened to the other nine.
Another warning, perhaps, not to take God's mercy for granted?
