John 7:37-39

37On the last and greatest day of the Feast, Yeshua stood up and cried out loudly, “If anyone is thirsty, let him come to Me and drink.

38Whoever believes in Me, as the Scripture says, ‘out of his innermost being will flow rivers of living water.’”

39Now He said this about the Ruach, whom those who trusted in Him were going to receive; for the Ruach was not yet given, since Yeshua was not yet glorified.
