John 4:13-14 (New Revised Standard Version)
Jesus said to her, "Everyone who drinks of this water will be thirsty again, but those who drink of the water that I will give them will never be thirsty. The water that I will give will become in them a spring of water gushing up to eternal life."
Isaiah 55:1-11 (New Revised Standard Version)
Ho, everyone who thirsts, come to the waters; and you that have no money, come, buy and eat! Come, buy wine and milk without money and without price. Why do you spend your money for that which is not bread, and your labor for that which does not satisfy? Listen carefully to me, and eat what is good, and delight yourselves in rich food. Incline your ear, and come to me; listen, so that you may live. I will make with you an everlasting covenant, my steadfast, sure love for David. See, I made him a witness to the peoples, a leader and commander for the peoples. See, you shall call nations that you do not know, and nations that do not know you shall run to you, because of the Lord your God, the Holy One of Israel, for he has glorified you. Seek the Lord while he may be found, call upon him while he is near; let the wicked forsake their way, and the unrighteous their thoughts; let them return to the Lord, that he may have mercy on them, and to our God, for he will abundantly pardon. For my thoughts are not your thoughts, nor are your ways my ways, says the Lord. For as the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts. For as the rain and the snow come down from heaven, and do not return there until they have watered the earth, making it bring forth and sprout, giving seed to the sower and bread to the eater, so shall my word be that goes out from my mouth; it shall not return to me empty, but it shall accomplish that which I purpose, and succeed in the thing for which I sent it.
