Jesus healed ten lepers, but only a non-Jewish one thanked him.

Luke 17:11-19

11 As Jesus and his disciples were walking along the road to Jerusalem, they were going through the region between Samaria and Galilee districts. 12 As they entered one village, ten lepers came near the road. Because lepers were not permitted to come near other people, they stood at some distance 13 and called out, “Jesus, Master, pity us and heal us!” 14 When he saw them, he said to them, “Each of you should go and show yourself to a priest in Jerusalem so that he can see if you are healed.” As they were going there, they were healed. 15 Then one of them, when he saw that he was healed, turned back, praising God loudly. 16 He came to Jesus, prostrated himself at Jesus’ feet, and thanked him. This man was a Samaritan, not a Jew. 17 Then Jesus said, “I healed ten lepers ◄I am disappointed that the other nine did not come back!/Where are the other nine?► [RHQ] 18 I am disappointed [RHQ] that this non-Jewish man was the only one who returned to thank God; none of the others came back to me!” 19 Then he said to the man, “Get up and continue on your journey. God [PRS] has saved you and healed you (sg) because you trusted in me.”
