Once, when Jesus was on the way to Jerusalem there met Him ten men that
were lepers, who stood afar off and lifted up their voice saying: Jesus,
Master, have mercy on us! He said: Go, and show yourselves to the
priests. And as they went, they were cleansed. One of them, when he saw
that he was healed, turned back, glorifying God with a loud voice. And
he fell upon his face at the feet of Jesus and gave Him thanks. And he
was a Samaritan. Then Jesus said: Were not the ten cleansed? But where
are the nine? Were there none found that returned to give glory to God,
save this stranger? And He said unto him: Arise, and go thy way; thy
faith hath made thee whole. (Luke 17:11-19.)
