《公冶長》 Passage 5.8
孟武伯問：「子路仁乎？」子曰：「不知也。」又問。子曰：「由也，千乘之國，可使治其賦也，不知其仁也。」「求也何如？」子曰：「求也，千室之邑，百乘之家，可使為之宰也，不知其仁也。」「赤也何如？」子曰：「赤也，束帶立於朝，可使與賓客言也，不知其仁也。」

"And what do you say of Qiu?" The Master replied: "In a city of a thousand families, or a clan of a hundred chariots, Qiu might be employed as governor, but I do not know whether he is perfectly virtuous."
"What do you say of Chi?" The Master replied: "With his sash girt and standing in a court, Chi might be employed to converse with the visitors and guests, but I do not know whether he is perfectly virtuous."
