Prayer of Azariah
The Prayer of Azariah and the Song of the Three Young Men is a Greek addition set inside Daniel 3, between the youths' entry into Nebuchadnezzar's furnace and their deliverance. Azariah confesses Israel's sins and pleads that contrite hearts be accepted where no sacrifice is possible; then, as an angel cools the flames, the three sing the Benedicite, summoning sun, stars, winds, seas, and all creation to bless the Lord. Catholics and Orthodox receive it as part of canonical Daniel; Protestants class it with the Apocrypha. Its canticle has been sung in Christian morning prayer for many centuries.
