What does Psalm 47:7 mean?

This verse affirms God's sovereignty over all the earth: His right to rule and use His creations as He sees fit. Therefore, the writer calls for praises in a specific way: with a maskiyl. This term is used in the description of various other psalms (Psalm 32:1; 42:1; 89:1). The word itself suggests something self-reflective. In this context, it might mean something more literal, such as skillful singing or musical play.

A prophetic glance into the future may come from the affirmation that that "God is the King of all the earth." God's universal kingdom refers now to His rule over everything. His mediatorial kingdom refers to His kingdom on earth under the rule of Jesus. Following the tribulation, the King of kings and Lord of lords will descend from heaven with His saint and angels, subdue His enemies, judge the nations, and establish His kingdom on earth (Revelation 19:11—21:4). Matthew 25:31–34 says all nations will gather before Him at His glorious return to earth. Saved people, depicted as sheep, will be welcomed into the kingdom. However, the unsaved people, represented as goats, will be banished from His presence to suffer eternal punishment (Matthew 25:41).
