We pass by, as not requiring more comment than we have already bestowed on a parallel passage (2 Sam. iii. 2-5), the unsavoury statement that "David took to him more concubines and wives" in Jerusalem. With all his light and grace, he had not overcome the prevalent notion that the dignity and resources of a kingdom were to be measured by the number and rank of the king's wives. The moral element involved in the arrangement he does not seem to have at all apprehended; and consequently, amid all the glory and prosperity that God has given him, he thoughtlessly multiplies the evil that was to spread havoc and desolation in his house.
We proceed, therefore, to what occupies the remainder of this chapter--the narrative of his wars with the Philistines. Two campaigns against these inveterate enemies of Israel are recorded, and the decisive encounter in both cases took place in the neighbourhood of Jerusalem.
The narrative is so brief that we have difficulty in apprehending all the circumstances. The first invasion of the Philistines took place soon after David was anointed king over all Israel. It is not said whether this occurred before David possessed himself of Mount Zion, nor, considering the structure common in Hebrew narrative, does the circumstance that in the history it follows that event prove that it was subsequent to it in the order of time. On the contrary, there is an expression that seems hardly consistent with this idea. We read (ver. 17) that when David heard of the invasion he "went _down_ into the hold." Now, this expression could not be used of the stronghold of Zion, for that hill is on the height of the central plateau, and invariably the Scriptures speak of "going up to Zion." If he had possession of Mount Zion, he would surely have gone to it when the Philistines took possession of the plain of Rephaim. The hold to which he went down must have been in a lower position; indeed, "the hold" is the expression used of the place or places of protection to which David resorted when he was pursued by Saul (see 1 Sam. xxii. 4). Further, when we turn to the twenty-third chapter of this book, which records some memorable incidents of the war with the Philistines, we find (vers. 13, 14) that when the Philistines pitched in the valley of Rephaim David was in a hold near the cave of Adullam. The valley of Rephaim, or "the giants," is an extensive plain to the south-west of Jerusalem, forming a great natural entrance to the city. When we duly consider the import of these facts, we see that the campaign was very serious, and David's difficulties very great. The Philistines were encamped in force on the summit of the plateau near the natural metropolis of the country. David was encamped in a hold in the low country in the south-west, making use of that very cave of Adullam where he had taken refuge in his conflicts with Saul. This was far from a hopeful state of matters. To the eye of man, his position may have appeared very desperate. 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.
