The phrase "Report to David" refers to the various instances in the biblical narrative where King David, the second king of Israel, receives reports or messages that significantly impact his reign and the history of Israel. These reports often come from military leaders, prophets, or other key figures and are pivotal in shaping the events of David's life and the nation of Israel.

1. Report of Saul's Death:
One of the most significant reports to David is the news of King Saul's death. In 2 Samuel 1:1-16, an Amalekite messenger brings David the report of Saul and Jonathan's deaths on Mount Gilboa. The messenger claims to have killed Saul at Saul's own request, hoping to gain favor with David. However, David mourns deeply for Saul and Jonathan and orders the execution of the messenger for killing the Lord's anointed. This report marks the transition of kingship from Saul to David, fulfilling God's promise to David.

2. Report of Absalom's Conspiracy:
Another critical report comes during the rebellion of Absalom, David's son. In 2 Samuel 15:13, a messenger informs David, "The hearts of the men of Israel are with Absalom." This report prompts David to flee Jerusalem to avoid confrontation and bloodshed in the city. The rebellion of Absalom is a significant event in David's reign, testing his leadership and faith in God's promises.

3. Report of Absalom's Death:
In 2 Samuel 18:31-33, David receives the report of Absalom's death from a Cushite messenger. Despite Absalom's rebellion, David is deeply grieved by the loss of his son, expressing his sorrow with the words, "O my son Absalom—my son, my son Absalom! If only I had died instead of you—O Absalom, my son, my son!" This report highlights David's complex character as both a king and a father, showcasing his deep emotional capacity and the personal cost of leadership.

4. Report of Bathsheba's Pregnancy:
In 2 Samuel 11:5, Bathsheba sends a report to David saying, "I am pregnant." This report follows David's sin of adultery with Bathsheba and sets off a chain of events leading to the murder of Uriah, Bathsheba's husband, and the subsequent judgment pronounced by the prophet Nathan. This incident is a turning point in David's life, leading to personal repentance and divine discipline.

5. Report of Nathan the Prophet:
Nathan the prophet delivers a report to David in 2 Samuel 12:1-14, confronting him about his sin with Bathsheba and Uriah. Nathan uses a parable to reveal David's wrongdoing, leading to David's confession and repentance. This report is crucial as it demonstrates God's justice and mercy, as well as the importance of accountability and repentance in the life of a believer.

6. Report of the Census:
In 2 Samuel 24:10, after David orders a census of Israel, he receives a report of the number of fighting men. However, David's conscience is troubled, and he realizes his sin in conducting the census, which was motivated by pride and a lack of trust in God. This report leads to David's repentance and God's subsequent judgment, which is mitigated by David's intercession.

Throughout these reports, we see the unfolding of God's sovereign plan in David's life and the nation of Israel. Each report serves as a reminder of the importance of obedience, repentance, and reliance on God, as well as the consequences of sin and the grace available through genuine repentance.
