2 Samuel 23:16

The host of the Philistines was in the valley of Rephaim, 2 Samuel 23:13, and in the way to Beth-lehem. He would not drink thereof; lest by gratifying himself upon such terms, he should seem either to set too high a price upon the satisfaction of his appetite, or too low a price upon the lives of his soldiers, or should encourage others to the like vain-glorious and foolish attempts. Poured it out unto the Lord, as a kind of drink-offering, and acknowledgment of God's goodness in preserving the lives of his captains in so dangerous an enterprise; and to show that he esteemed it as a sacred thing, which, considering all things, it was not fit for him to drink it.
