Such an emergency was a fit time for a solemn application to God for direction. "David inquired of the Lord, saying, Shall I go up to the Philistines? Wilt Thou deliver them into mine hand? And the Lord said unto David, Go up, for I will doubtless deliver the Philistines into thine hand." Up, accordingly, David went, attacked the Philistines and smote them at a place called Baal-perazim, somewhere most likely between Adullam and Jerusalem. The expression "The Lord hath broken forth on mine enemies before me, as the breach of waters," seems to imply that He broke the Philistine host into two, like flooded water breaking an embankment, preventing them from uniting and rallying, and sending them in two detachments into flight and confusion. Considering the superior position of the Philistines, and the great advantage they seem to have had over David in numbers also, this was a signal victory, even though it did not reduce the foe to helplessness. For when the Philistines had got time to recover, they again came up, pitched again in the plain of Rephaim, and appeared to render unavailing the signal achievement of David at Baal-perazim. Again David inquired what he should do. The reply was somewhat different from before. David was not to go straight up to face the enemy, as he had done before. He was to "fetch a compass behind them," that is, as we understand it, to make a circuit, so as to get in the enemy's rear over against a grove of mulberry trees. That tree has not yet disappeared from the neighbourhood of Jerusalem; a mulberry tree still marks the spot in the valley of Jehoshaphat where, according to tradition, Isaiah was sawn asunder (Stanley's "Sinai and Palestine"). When he should hear "the sound of a going" (Revised Version, "the sound of a march") in the tops of the mulberry trees, then he was to bestir himself. It is difficult to conceive any natural cause that should give rise to a sound like that of a march "in the tops of the mulberry trees;" but if not a natural, it must have been a supernatural indication of some sound that would alarm the Philistines and make the moment favourable for an attack. It is probable that the presence of David and his troop in the rear of the Philistines was not suspected, the mulberry trees forming a screen between them. When David got his opportunity, he availed himself of it to great advantage; he inflicted a thorough defeat on the Philistines, and smiting them from Geba to Gazer, he appears to have all but annihilated their force. In this way, he gave the _coup de grâce_ to his former allies.
