Luke 17:11-17

And it came to pass, as they were on the way to Jerusalem, that he was passing along the borders of Samaria and Galilee. And as he entered into a certain village, there met him ten men that were lepers, who stood afar off: and they lifted up their voices, saying, Jesus, Master, have mercy on us. And when he saw them, he said unto them, Go and show yourselves unto the priests. And it came to pass, as they went, they were cleansed. And one of them, when he saw that he was healed, turned back, with a loud voice glorifying God; and he fell upon his face at his feet, giving him thanks: and he was a Samaritan. And Jesus answering said, Were not the ten cleansed? but where are the nine?
