Story of One who was not what he seemed

Some one passed by a pious man whom he took for a Jew, and, therefore, struck him on the neck. The latter bestowed his robe upon the aggressor, who, becoming ashamed, remarked:

“I acted wrongly and thou hast forgiven me. But what occasion is this for a gift?”

“I stood not up in anger,” was the reply, “being thankful that I was not a Jew, as thou didst suppose.”
