Isaiah 26:3-5

New Revised Standard Version Catholic Edition

³ Those of steadfast mind you keep in peace—
    in peace because they trust in you.
⁴ Trust in the Lord forever,
    for in the Lord God^[a]
    you have an everlasting rock.
⁵ For he has brought low
    the inhabitants of the height;
    the lofty city he lays low.
He lays it low to the ground,
    casts it to the dust.
