Charles Ellicott Commentary Psalms 87:5

"Yea, of Zion it shall be said, This one and that one was born in her; And the Most High himself will establish her." — Psalms 87:5 (ASV)

And of Zion ... —This verse must be taken as antithetical to the preceding. The poet claims a prouder boast for natives of Jerusalem, because it was established by the Most High. It is rendered: But of Zion it is said, "This man and that (literally, man and man) was born in her, and her the Most High established."
