Feeding the hungry is a recurring theme in the Bible. Jesus fed the crowds on two occasions with fish and bread and also described himself as "the bread of life."
In another well known Bible passage Jesus tells a story where people that feed the hungry are praised by God:
Then the King will say to those on his right, ‘Come, you who are blessed by my Father, inherit the kingdom prepared for you from the foundation of the world. For I was hungry and you gave me food, I was thirsty and you gave me drink, I was a stranger and you welcomed me, I was naked and you clothed me, I was sick and you visited me, I was in prison and you came to me.’ - Matthew 25:34-36 ESV
