The Three Warriors sneaked into the Philistine camp and got some water from the well near Bethlehem's gate. But after they brought the water back to David, he refused to drink it. Instead, he poured it out as a sacrifice
(A psalm by David when he was in the desert of Judah.) You are my God. I worship you. In my heart, I long for you, as I would long for a stream in a scorching desert.
Jesus answered, "You don't know what God wants to give you, and you don't know who is asking you for a drink. If you did, you would ask me for the water that gives life."
