Martin of Tours (AD 316–397) was Bishop of Tours, France, from AD 371. One very cold night, riding on horseback, he passed a beggar. Martin got off his horse, tore his robe in two and gave half of it to the beggar. That night, Martin had a dream in which he saw Jesus wearing the robe that had been torn in two on his shoulders. When asked where it had come from, Jesus replied, ‘My servant Martin gave it to me.’ Jesus said, “And if anyone gives even a cup of cold water to one of these little ones who is my disciple, truly I tell you, that person will certainly not lose their reward.” (Matthew 10:42)
