2nd Samuel 5:7 Nevertheless David took the strong hold of Zion: the same is the city of David.
[Patriarchs & Prophets pp 703] Eight hundred years before the coronation of David it had been the home of Melchizedek, the priest of the most high God. It held a central and elevated position in the country and was protected by an environment of hills. Being on the border between Benjamin and Judah, it was in close proximity to Ephraim and was easy of access to the other tribes.
In order to secure this location the Hebrews must dispossess a remnant of the Canaanites, who held a fortified position on the mountains of Zion and Moriah. This stronghold was called Jebus, and its inhabitants were known as Jebusites. For centuries Jebus had been looked upon as impregnable; but it was besieged and taken by the Hebrews under the command of Joab, who, as the reward of his valor, was made commander-in-chief of the armies of Israel.
Jebus now became the national capital, and its heathen name was changed to Jerusalem. Hiram, king of the wealthy city of Tyre, on the Mediterranean Sea, now sought an alliance with the king of Israel, and lent his aid to David in the work of erecting a palace at Jerusalem. Ambassadors were sent from Tyre, accompanied by architects and workmen and long trains laden with costly wood, cedar trees, and other valuable material.
2nd Samuel 5:10 And David went on, and grew great, and the Lord God of hosts was with him. 11 And Hiram king of Tyre sent messengers to David, and cedar trees, and carpenters, and masons: and they built David an house.
May The Lord add His blessing to the study of His word. God bless!
