Under the monarchy that replaced Israel's theocracy, God chose David of the tribe of Judah to succeed Saul. As recorded in II Samuel 5:4-5, David ruled for seven and a half years over Judah from Hebron. Following the end of Saul's dynasty, all the elders of Israel came to Hebron, and David made a covenant with them before the Lord, after which they anointed him king over all Israel. David took significant steps by establishing a house for himself in Jerusalem, which became the capital of the Kingdom of Israel, uniting all the tribes under his rule. God's response to David's desire to build a Temple included a profound promise through the prophet Nathan, highlighting the enduring significance of David's lineage and throne.

David, as a king from the tribe of Judah, exemplifies the qualities and challenges of monarchy as outlined in God's plan. He was raised up by God as a ruler through whom the Messiah would ultimately come, fulfilling the prophecy that the scepter would not depart from Judah. During his reign of about 40 years, David faced numerous enemies and difficult positions, yet he frequently trusted God for deliverance, setting a powerful example of reliance on divine strength rather than worldly might. In II Samuel 22:31-35, David acknowledges God as his strength and power, declaring that God's way is perfect and that He is a shield to all who trust in Him. He credits God with teaching him to make war and providing the ability to overcome challenges, rather than amassing horses or seeking alliances with foreign powers like Egypt or Assyria. Further, in II Samuel 22:36-37, David recognizes God's salvation and gentleness as the source of his greatness, ensuring his path remains secure. Though David made mistakes, he learned from them, ultimately trusting in God, which marks him as one of the good kings. His example teaches that even in battle, while enemies remain and fighting is necessary, it is God who provides the winning difference. This trust in God, rather than in military might or personal power, is a key lesson for future rulers preparing to serve in God's kingdom.

David is known primarily as a warrior and king. His conquests and reign established the Golden Age of Israelite history. He yearned for God's direct rule over not just Israel but the whole earth. Because of his zeal for Him and His Kingdom God used David mightily as a prophet to flesh out many of those promises in his writings the Psalms.
