“God upholds his city forever.” Really?

The Lord is great and worthy to be praised
in the city of our God.
His holy mountain rises in beauty,
the joy of all the earth.

God upholds his city for ever.

Mount Zion, true pole of the earth,
the Great King’s city!
God, in the midst of its citadels,
has shown himself its stronghold.

God upholds his city for ever.

For the kings assembled together,
together they advanced.
They saw; at once they were astounded;
dismayed, they fled in fear.

God upholds his city for ever.

A trembling seized them there,
like the pangs of birth.
By the east wind you have destroyed
the ships of Tarshish.

God upholds his city for ever.
