George Rohr is a businessman who has been inspired by the Rebbe, and who supports many Lubavitch activities. Once, before Yom Kippur, when receiving
lekach (honey cake) from the Rebbe, it occurred to him that he should give something to the Rebbe and not merely take from him. With that thought in mind, he told the Rebbe that for Rosh HaShanah, he had organized a
minyan for over 130 Jews who had no Jewish background.
The Rebbe immediately became serious. "With no Jewish background?" he repeated, looking at Mr. Rohr intently.
Not understanding what he had said wrong, Mr. Rohr could only say again, "With no background."
"Go back and tell them," the Rebbe said, "that they have a Jewish background! They have the background of Avraham, Yitzchak and Yaakov."
