2nd Samuel 5:4 David was thirty years old when he began to reign, and he reigned forty years. 5 In Hebron he reigned over Judah seven years and six months: and in Jerusalem he reigned thirty and three years over all Israel and Judah.
[Patriarchs & Prophets pp 703] As soon as David was established on the throne of Israel he began to seek a more appropriate location for the capital of his realm. Twenty miles from Hebron a place was selected as the future metropolis of the kingdom. Before Joshua had led the armies of Israel over Jordan it had been called Salem. Near this place Abraham had proved his loyalty to God. 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 5:11 And Hiram king of Tyre sent messengers to David, and cedar trees, and carpenters, and masons: and they built David an house. 12 And David perceived that the Lord had established him king over Israel, and that he had exalted his kingdom for his people Israel's sake.
May The Lord add His blessing to the study of His word. God bless!
