How do we know Jesus is a king according to the Bible?

Jesus is recognized as God's King in numerous biblical passages, including Psalm 2, which states that God has set His King upon His holy hill. This designation aligns with God's choice of David as king, as David is seen as a type of Christ. In 1 Samuel 16:1, God declares to Samuel that He has provided a king, which ultimately points to Jesus, the King of Kings. This concept is enriched in the New Testament where Jesus is acknowledged as a descendant of David (Matthew 1:1), fulfilling God's covenant promises while embodying the role of shepherd king (John 10:11). His kingly authority is crucial for providing salvation and shepherding His people.
