Psalm 47, often identified as Psalm 46 in the Septuagint and Vulgate, is a jubilant hymn of praise celebrating God's universal sovereignty. Although its superscription attributes it "To the choirmaster. Of the Sons of Korah. A Psalm," suggesting a liturgical context involving a guild of temple musicians, its themes resonate deeply with royal psalms and those depicting God's enthronement. Composed during a period when Israel experienced God's powerful intervention—perhaps after a significant victory or a miraculous deliverance—the psalm exalts the Lord as King over all the earth. Its historical origins are often linked to ancient Near Eastern enthronement festivals, where the deity's cosmic reign was proclaimed and celebrated.

The psalm opens with a call for all peoples to "Clap your hands, all you nations; shout to God with cries of joy." This universal acclamation sets the tone for a cosmic celebration of God's dominion. Key verses, such as "God has ascended amid shouts of joy, the Lord amid the sounding of trumpets," vividly portray a triumphal procession. This imagery suggests God's victorious return to His heavenly throne after a great act of salvation or judgment. The repetition of God's kingship ("God is King over all the earth") reinforces the central theological message: God's ultimate authority extends beyond Israel to encompass all humanity and creation.

In Christian tradition, Psalm 47 takes on profound messianic significance, particularly for the Feast of the Ascension of the Lord. The exclamation "God has ascended" is directly interpreted as a prophetic foreshadowing of Christ's bodily ascent into heaven, forty days after His resurrection. This event, narrated in Acts 1:9-11, marks the culmination of Jesus' earthly ministry and His enthronement at the right hand of the Father. The psalm's depiction of God's universal kingship finds its ultimate fulfillment in Christ, to whom "all authority in heaven and on earth has been given" (Matthew 28:18). For the Mass of the Ascension, Psalm 47 serves as the responsorial psalm, with the refrain "God mounts his throne to shouts of joy: a blare of trumpets for the Lord" (from verse 6). This solemnity celebrates Christ's exaltation, His intercession for humanity, and the promise of His return. The psalm thus enriches the feast by inviting believers to join in the cosmic chorus of praise for Christ, the ascended King and Lord of all.
