Zion registers peoples as native-born

Zion is loved as a founded city, and glorious things are spoken of her

His foundation is in the holy mountains. The LORD loveth the gates of Zion more than all the dwellings of Jacob. Glorious things are spoken of thee, O city of God. The preference is the LORD's love for Zion's gates, not a ranking of people by neighborhood. Jacob's other dwellings remain dwellings; Zion is named as the city of God.

Former rivals are registered as native-born on the city's roll

I will make mention of Rahab and Babylon to them that know me: behold Philistia, and Tyre, with Ethiopia; this man was born there. And of Zion it shall be said, This and that man was born in her: and the highest himself shall establish her. The LORD shall count, when he writeth up the people, that this man was born there. As well the singers as the players on instruments shall be there: all my springs are in thee.

Rahab here is Egypt in poetic dress, named with Babylon, Philistia, Tyre, and Cush. The shock is the birth certificate: people from rival powers counted as born in Zion when the LORD writes up the peoples. Singers and players answer from springs in her. The image is belonging imagined among former enemies. It must not become ethnic exclusion, a boast that only some bloodlines count, or supersession that erases Jewish Zion in order to claim the register for someone else.
