What does the Bible say about the kingship of David?

David's kingship is established in 2 Samuel 2:1-11, where he seeks the Lord's guidance before ascending to claim his rightful place as king over Judah. After Saul's death, the men of Judah anoint David, validating God's promise that the kingdom would come through the tribe of Judah, as foretold by Jacob in Genesis 49:10. David's anointing illustrates how God appoints leaders to fulfill His will and encompasses the larger narrative that points to Christ, known as the rightful king who reigns eternally. This foreshadowing of Christ's sovereignty highlights how God works through history to fulfill His divine plans.
