다윗이 온 이스라엘로 더불어 예루살렘 곧 여부스에 이르니 여부스 토인이 거기 거하였더라

And the king and his men went to Jerusalem – In Divre HaYamim it says “And David and all of Israel went to Jerusalem…” (Divre HaYamim I 11:4) because now all of Israel were his men. Since he was now king over all of Israel he went to Jerusalem to conquer the citadel of Zion because they had a tradition that Zion was the head of kingship in Israel and only one who was king over all of Israel would conquer. Unto this day there had not been full kingship in Israel because Shaul’s kingship was not permanently established.
