In the Gospels

Luke 17:11-19

It happened as he was on his way to Jerusalem, that he was passing along the borders of Samaria and Galilee. As he entered into a certain village, ten men who were lepers met him, who stood at a distance. They lifted up their voices, saying, Jesus, Master, have mercy on us!

When he saw them, he said to them, Go and show yourselves to the priests. It happened that as they went, they were cleansed. One of them, when he saw that he was healed, turned back, glorifying God with a loud voice. He fell on his face at Jesus’ feet, giving him thanks, and he was a Samaritan. Jesus answered, Weren’t the ten cleansed? But where are the nine? Were there none found who returned to give glory to God, except this stranger? Then he said to him, Get up, and go your way. Your faith has healed you.
