For Zion's sake I will not keep silent,
for Jerusalem's sake I will not remain quiet,
till her righteousness shines out like the dawn,
her salvation like a blazing torch.

I have posted watchmen on your walls, O Jerusalem;
they will never be silent day or night.
You who call on the LORD,
give yourselves no rest,

and give him no rest till he establishes Jerusalem
and makes her the praise of the earth.

Isaiah 62:1, 6-7
