John 7:37-38

Now on the last and most important day of the feast, Jesus stood and called out [in a loud voice], “If anyone is thirsty, let him come to Me and drink! He who believes in Me [who adheres to, trusts in, and relies on Me], as the Scripture has said, ‘From his innermost being will flow continually rivers of living water.’ ” [Is 58:11; John 4:14]
