Whoever believes in me, as the Scripture has said, ‘Out of
his heart will flow rivers of living water.’” John 7:38
Jesus said to her, “Everyone who drinks of this water will be thirsty again, but whoever drinks of the water that I will give him will never be thirsty again. The water that I will give him will become in him a spring of water welling up to eternal life.” John 4:13b-14
And he said to me, “It is done! I am the Alpha and the Omega, the beginning and the end. To the thirsty I will give from the spring of the water of life without payment." Rev 21:6
The Spirit and the Bride say, “Come.” And let the one who hears say,“Come.” And let the one who is thirsty come; let the one who desires take the water of life without price. Rev 22:17
With joy you will draw water from the wells of salvation. Isa 12:3
Then the angel showed me the river of the water of life, bright as crystal, flowing from the throne of God and of the Lamb Rev 22:1
On the last and greatest day of the festival, Jesus stood and said in a loud voice, “Let anyone who is thirsty come to me and drink. Whoever believes in me, as Scripture has said, rivers of living water will flow from within them.” By this he meant the Spirit, whom those who believed in him were later to receive. John 7:37-39a
They shall hunger no more, neither thirst anymore; the sun shall not strike them, nor any scorching heat. For the Lamb in the midst of the throne will be their shepherd, and he will guide them to springs of living water, and God will wipe away every tear from their eyes. Rev 7:16-17
Jesus answered her, “If you knew the gift of God, and who it is that is saying to you, ‘Give me a drink,’ you would have asked him, and he would have given you living water.” John 4:10
