1 Chronicles 14:13

And the Philistines came up yet again, and spread themselves in the valley of Rephaim. And when David inquired of the LORD, he said, Thou shalt not go up; but fetch a compass behind them, and come upon them over against the mulberry trees. And let it be, when thou hearest the sound of a going in the tops of the mulberry trees, that then thou shalt bestir thyself: for then shall the LORD go out before thee, to smite the host of the Philistines. And David did so, as the LORD had commanded him; and smote the Philistines from Geba until thou come to Gazer.

And the prophet came to the king of Israel, and said unto him, Go, strengthen thyself, and mark, and see what thou doest: for at the return of the year the king of Syria will come up against thee.

And the Philistines came and spread themselves in the valley of Rephaim.
