Psalm 87: There are no Gentile.

Verse 4: "I will record Rahab and Babylon as those who know me; Philistia, Tyre, and Ethiopia will be said to have been born in Zion."

According to verse 4, Israel and the surrounding nations are all within God's embrace. This is the worldview and faith of the poet. In comparison to the 'Adam-Christ-Typology', Israel represents all nations. We commonly refer to nations other than Israel as foreign nations, but according to the description in Psalm 87, the distinction between them is meaningless. There are no boundaries for foreign nations or foreigners. Everyone is a brother and sister within God.
