There is a story recorded about a day David was thirsty. He was surrounded by his enemy, the Philistines, and said, "Oh, that someone would get me a drink of water from the well near the gate of Bethlehem"(where it just so happened to be where the Philistines were). The story goes then "So the Three broke through the Philistine lines, drew water from the well near the gate of Bethlehem and carried it back to David."
But what did David do? His "Three" risked their lives for their leader's thirst and when they brought it to him, "he refused to drink it; instead, he poured it out before the LORD. 'God forbid that I should do this!' he said. 'Should I drink the blood of these men who went at the risk of their lives?' Because they risked their lives to bring it back, David would not drink it."
The leadership of David was such that the Three risked their lives for his thirst to be quenched.
