"But you, O LORD, sit enthroned forever, 
your renown endures through all generations.
You will arise and have compassion on Zion,
for it is time to show favor to her; the appointed time has come.
For her stones are dear to your servants;
her very dust moves them to pity.
The nations will fear the name of the LORD,
all the kings of the earth will revere your glory.
For the LORD will rebuild Zion and appear in his glory.
He will respond to the prayer of the destitute;
he will not despise their plea.
Let this be written for a future generation,
that a people not yet created may praise the LORD"
Psalm 102:12-18
