Tertullian : God is not offering his services as a water manager or a farmer when he says, "I will open rivers in a dry land; I will plant in the wilderness the cedar and the box tree." — AGAINST MARCION 3.5 Theodoret of Cyrus : He refers in this way to those who have been entrusted with the grace of instruction. For he has said in the holy Gospels: "He who believes in me, as the Scripture has said, out of his heart will flow rivers of living water." "I will make the desert pools of water and a parched land springs." He gives the name "desert" to the Gentiles; this promise had been made to them similarly in the preceding passages. — COMMENTARY ON Isaiah 12:41.18
