Behold Zion, the city of our appointed feasts!
Your eyes will see Jerusalem,
an untroubled habitation, an immovable tent,
whose stakes will never be plucked up,
nor will any of its cords be broken.
But there the Lord in majesty will be for us
a place of broad rivers and streams,
where no galley with oars can go,
nor majestic ship can pass.
Isaiah 33:20-21

Blessed be the LORD,
marvelously he showed to me
his mercy in a fortified city.
Psalms 31: 3, 20

As the mountains surround Jerusalem, so the LORD surrounds his people both now and forevermore.
Psalm 125:2
