Wherever the Chofetz Chaim (R. Yisroel Meir HaKohen) traveled he brought a new, long black coat, packed in a suitcase. Once, one of his close acquaintances asked: ‘Why don’t you ever wear your new coat?’ The Chofetz Chaim replied: ‘I truly believe that Moshiach will come any day now, and I want to be sure that as soon as he comes I will be able to greet him with this new garment.’
