Explanation

First Chronicles 17:13 describes the special covenant relationship between God and David's royal heir: "I will be his father, and he shall be my son." In its immediate historical setting, this father-son language applies to Solomon as the divinely chosen Davidic king. It expresses royal covenant sonship and God's commitment to the dynasty rather than teaching that Solomon was divine.

Hebrews 1:5 directly quotes this promise and applies it to Jesus while demonstrating the superiority of the Son over the angels. This gives the passage an explicit New Testament Christological fulfillment. The royal sonship represented historically by Solomon and the Davidic kings reaches its fullest reality in Christ, who is not merely an adopted royal representative but the unique Son of God and eternal Davidic King. First Chronicles is especially suggestive in this regard because, unlike the parallel passage in 2 Samuel, it omits the statement about disciplining the royal son for wrongdoing and emphasizes instead the enduring divine mercy and permanence of his throne.
