"Eliach added: 'See, you do a favor for a Jew and he always remembers. I hope the pope is listening and he does us another favor — he recognizes Israel.' He did! He even left a kvitl (message) at the Kotel." (source)
"We were already outside the Rebbe’s room when Leibel Groner, who died this past April, asked for the kvitl. When I said I didn’t have one – aside from which anything I had to discuss with the Rebbe was of a personal nature – Leibel Groner said that if I didn’t have a kvitl, I couldn’t go in." (source)
