How do we know Christ is the subject of Psalm 16?

The identification of Christ as the central figure in Psalm 16 is made clear through prophetic foreshadowing and explicit New Testament confirmation. Verses 8 and 11 in the Psalm poignantly declare attributes associated with Christ, such as His resurrection and holiness. Acts 2:25-28 and Acts 13:35-37 affirm this by directly referencing the Psalm and attributing its claims to Jesus Christ, the Holy One who was raised from the dead and did not see corruption. Therefore, while David penned the Psalm, the reality points towards Christ, making His life and work the focal point of its message.
