The psalm begins with a statement: his foundation is on the holy mount. The Lord loves the gates of Zion more than all the dwelling places of Jacob. Glorious things are spoken of you, O city of God.
In verse 4, God himself speaks: among those who know me I record Rahab and Babylon. Rahab is a poetic name for Egypt, and Babylon was an enemy power. Also Philistia, Tyre and Cush: this one was born there. It is startling that peoples who were adversaries or strangers are counted as born in Zion.
Verses 5 and 6 widen the idea: of Zion it shall be said that this one and that one were born in her, and the Most High himself will establish her. The Lord records, as he registers the peoples: this one was born there. It is a picture of a register of citizens, where God enrolls people of all nations as inhabitants of his city.
Verse 7 concludes with singers and players who declare: all my springs are in you. Zion is the place from which life flows for those who belong to it.
