Sirach 48:21-23

New Revised Standard Version, Anglicised Catholic Edition

²¹ The Lord^[a] struck down the camp of the Assyrians,
    and his angel wiped them out.
²² For Hezekiah did what was pleasing to the Lord,
    and he kept firmly to the ways of his ancestor David,
as he was commanded by the prophet Isaiah,
    who was great and trustworthy in his visions.

²³ In Isaiah’s^[b] days the sun went backwards,
    and he prolonged the life of the king.
