1 Samuel 18-19; 1 Chronicles 3; Psalm 59; Acts 13

The story of Saul and David's relationship contains several important truths:

- There's a stark contrast between Saul and David's personalities. David lives relying on God, while Saul relies on himself, his strength, and his abilities.
- Saul doesn't know what to do with David; he envies him, fears him, schemes against him, and tries to kill him.
- David, trusting in God, acts wisely everywhere.
- Saul is emotionally unstable, having opened his heart to evil. An evil spirit from the Lord” - God allows the influence of an evil spirit in a heart open to evil.
- Despite the threat from Saul, David continues to fulfill his task -”protecting Israel from the Philistines” and doesn't see himself as anyone great.

The Books of Chronicles cover a period of Israel's history parallel to 2-4 Kings. Unlike the Books of Kings, they were written by priests (possibly Ezra) and show the establishment of David's kingdom and the further development of his throne. They emphasize hope for the restoration of the kingdom.

1 Chronicles 3 provides a complete list of David's children, giving an account of his family.

Psalm 59 reflects David's state when Saul sent to kill him. He understands his dependence on God -“My strength, I will wait for You..." (Psalm 59:10). Asking for protection, he speaks of the main goal ”…that they may know that God rules in Jacob to the ends of the earth" (Psalm 59:14). Saul's problem is evident to him. The King of Israel doesn't know the strength of God and His rule.

Acts 13 describes the beginning of the apostle Paul's first missionary journey. It begins with the Holy Spirit's command in Antioch during Paul's ministry there. It provides a detailed account of Paul's first sermon. Like Peter's sermons, it focuses on the history of Israel and leads to the historical, biblical, and factual justification that Jesus of Nazareth is the promised Messiah appointed by God. The key point of the sermon: "Therefore, let it be known to you, brethren, that through this Man is preached to you the forgiveness of sins; and by Him, everyone who believes is justified from all things from which the law of Moses could not justify you" (Acts 13:39) - ”clear teaching on substitutionary atonement is preached from the very beginning.

Another important verse speaks of God's election unto salvation - ”...as many as had been appointed to eternal life believed" (Acts 13:48).
