In the first place, David was forced to break with the Philistines, if he wished to be independent, and to win back the love of his people. He had to prepare himself for fierce warfare with his former auxiliaries. But he did not immediately commence hostilities with them; they were too powerful for him. He wished first to free himself from other bonds. In the midst of the Benjamite territory was an enclosure, which had remained in the possession of the Jebusites, because the Israelites, on their entry into the land, had not conquered it. The high hill of Zion was rendered inaccessible on three sides by narrow valleys and artificial fortifications. The most impregnable point was the south side, where the rocky wall of the hill rose almost in a vertical line from an abyss below. From this mountain fortress, the Jebusites ruled the entire surrounding territory, and felt themselves secure from all intruders. They appear to have lived in a state of peace with the surrounding Benjamites and Judæans, as even Saul did not disturb them in the possession of their territory. David, however, considered it conducive to his interest to obtain possession of this citadel of Zion before commencing hostilities with the Philistines. He therefore resolved to storm the citadel, and subdue its defenders. As soon as the Jebusites found all opposition useless they sued for peace, which was granted them by David. They were allowed to remain in their city, but not in the fortress; he permitted them to settle in the east of the town, on Mount Moriah. This victory, which had appeared so difficult, and had, in fact, been easily obtained, had been preceded by the boast of the Jebusites about the blind and the lame, which gave rise to a proverb.
