3 When all the elders of Israel had come to King David at Hebron, the king made a covenant with them at Hebron before the Lord, and they anointed David king over Israel.
4 David was thirty years old when he became king, and he reigned forty years. 5 In Hebron he reigned over Judah seven years and six months, and in Jerusalem he reigned over all Israel and Judah thirty-three years.
David Conquers Jerusalem
6 The king and his men marched to Jerusalem to attack the Jebusites, who lived there. The Jebusites said to David, “You will not get in here; even the blind and the lame can ward you off.” They thought, “David cannot get in here.” 7 Nevertheless, David captured the fortress of Zion—which is the City of David.
8 On that day David had said, “Anyone who conquers the Jebusites will have to use the water shaft to reach those ‘lame and blind’ who are David’s enemies.” That is why they say, “The ‘blind and lame’ will not enter the palace.”
9 David then took up residence in the fortress and called it the City of David. He built up the area around it, from the terraces inward.
The fortress of Zion became the city of Jerusalem. It is located near a high ridge at the center of the united Israelite kingdom. Jerusalem sits on a high ridge, and back in David’s time, it made it difficult to attack. The walls of Zion were fortified, but David chose a different way to get into Zion. He entered through the city water tunnel. We need to know that only in God are we truly safe and secure. Anything else is false security. We cannot predict tomorrow. Your relationship with God is the only security that cannot be snatched away from you. Once you belong to Jesus, and he belongs to you, you can never be taken from him. That is a wonderful security to have.
