Luke 17:12
And as He entered a certain village, He was met by ten men with infectious skin diseases, who were standing some distance away [Note: Restrictions in the Jewish law prevented contact with persons having infectious diseases. See Lev. 13:45ff],
Luke 5:12
And it happened while Jesus was in one of the towns [i.e., surrounding Lake Galilee], that a man covered with an infectious skin disease appeared and, when he saw Jesus, he fell on his face [to the ground] and begged Him, saying, "If you want to, you can heal me." [Note: Throughout this narrative the terms "heal/healing" are originally "clean/cleansing" because the Jews viewed a person with such a disease as ceremonially "unclean." See Lev. 13:1-3].
Luke 18:13
But the tax collector stood at a distance [i.e., inconspicuously] and would not even look up to heaven, but struck his chest [i.e., in remorse], saying, 'God, [please] have mercy on a sinner like me.'
