2 Samuel 23:1-7, 13-17
Now these are the last words of David: The oracle of David, the son of Jesse, the oracle of the man who was raised on high, the anointed of the God of Jacob, the sweet psalmist of Israel:
"The Spirit of the LORD speaks by me, his word is upon my tongue. The God of Israel has spoken, the Rock of Israel has said to me: When one rules justly over men, ruling in the fear of God, he dawns on them like the morning light, like the sun shining forth upon a cloudless morning, like rain that makes grass to sprout from the earth. Yea, does not my house stand so with God? For he has made with me an everlasting covenant, ordered in all things and secure. For will he not cause to prosper all my help and my desire? But godless men are all like thorns that are thrown away; for they cannot be taken with the hand; but the man who touches them arms himself with iron and the shaft of a spear, and they are utterly consumed with fire."
And three of the thirty chief men went down, and came about harvest time to David at the cave of Adullam, when a band of Philistines was encamped in the valley of Reph'aim. David was then in the stronghold; and the garrison of the Philistines was then at Bethlehem. And David said longingly, "O that some one would give me water to drink from the well of Bethlehem which is by the gate!" Then the three mighty men broke through the camp of the Philistines, and drew water out of the well of Bethlehem which was by the gate, and took and brought it to David. But he would not drink of it; he poured it out to the LORD, and said, "Far be it from me, O LORD, that I should do this. Shall I drink the blood of the men who went at the risk of their lives?" Therefore he would not drink it. These things did the three mighty men.
