There was a boy who had only two fish & five loaves of bread he gave the five and loaves unto the lord Jesus and in turn he lifted them up towards heaven he gave thanks to the father above and inturn god multiplied the fish and loaves. That was one of many miracles the lord did. This story is found in the new testament.
