Now on the last day, the great day of the feast, Jesus stood and cried out, saying, "If anyone is thirsty, let him come to Me and drink. 'He who believes in Me, as the Scripture said, `From his innermost being will flow rivers of living water.'"

The feast that Jesus attended was Sukkot, the great harvest feast of the year.
