'Fast' in the Bible

Jesus saith unto them, Come and break your fast. And none of the disciples durst inquire of him, Who art thou? knowing that it was the Lord.

So when they had broken their fast, Jesus saith to Simon Peter, Simon,'son of John, lovest thou me more than these? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my lambs.
