Introduction:
David, the son of Jesse, is one of the most significant figures in the Bible, known for his profound faith, military prowess, and poetic contributions to the Psalms. His anointing as king over all Israel marks a pivotal moment in biblical history, uniting the tribes under a single monarch and establishing Jerusalem as the political and spiritual center of the nation.

Biblical Context:
David's journey to kingship begins with his anointing by the prophet Samuel while Saul was still king (1 Samuel 16:1-13). Despite being chosen by God, David faced numerous challenges, including Saul's jealousy and attempts on his life. After Saul's death, David was initially anointed king over the tribe of Judah in Hebron (2 Samuel 2:4). It was not until later that he was recognized as king over all Israel.

Anointing as King of All Israel:
The account of David's anointing as king over all Israel is found in 2 Samuel 5:1-5 and 1 Chronicles 11:1-3. The tribes of Israel came to David at Hebron, acknowledging his leadership and God's promise to him. They declared, "Behold, we are your own flesh and blood. Even in times past, while Saul was king over us, you were the one who led Israel out and brought them back. And the LORD said to you, 'You will shepherd My people Israel, and you will be ruler over them.'" (2 Samuel 5:1-2).

Significance of the Anointing:
David's anointing as king over all Israel is significant for several reasons:

1. Fulfillment of God's Promise: David's anointing fulfills God's promise to establish his kingdom, as prophesied by Samuel. It marks the beginning of the Davidic dynasty, which is central to the messianic hope in the Old Testament.

2. Unity of the Tribes: David's acceptance by all the tribes signifies the unification of Israel, which had been divided during Saul's reign. This unity is crucial for the nation's strength and stability.

3. Establishment of Jerusalem: Following his anointing, David captures Jerusalem and establishes it as the capital city (2 Samuel 5:6-10). This strategic and spiritual center becomes the site of the future temple and the heart of Israelite worship.

4. David's Covenant with God: David's reign is marked by a covenant with God, promising that his descendants would rule Israel forever (2 Samuel 7:12-16). This covenant is foundational for the messianic prophecies concerning Jesus Christ, who is often referred to as the "Son of David."

David's Reign:
David's reign over all Israel is characterized by military victories, territorial expansion, and religious reforms. He brings the Ark of the Covenant to Jerusalem, establishing it as the religious center of the nation (2 Samuel 6). Despite personal failings and family strife, David is remembered as a man after God's own heart (1 Samuel 13:14), whose psalms continue to inspire worship and devotion.

Conclusion:
David's anointing as king over all Israel is a defining moment in biblical history, setting the stage for the future of the Israelite nation and the coming of the Messiah. His legacy as a warrior, poet, and king endures as a testament to God's faithfulness and the enduring hope of redemption through the line of David.
