Tobit 13:6
4 He has shown you his greatness even there. Exalt him in the presence of every living being, because he is our Lord and he is our God; he is our Father and he is God forever. 5 He will afflict you for your iniquities, but he will again show mercy on all of you. He will gather you from all the nations among whom you have been scattered. 6 If you turn to him with all your heart and with all your soul, to do what is true before him, then he will turn to you and will no longer hide his face from you. So now see what he has done for you; acknowledge him at the top of your voice. Bless the Lord of righteousness, and exalt the King of the ages. In the land of my exile I acknowledge him, and show his power and majesty to a nation of sinners: "Turn back, you sinners, and do what is right before him; perhaps he may look with favor upon you and show you mercy.' 7 As for me, I exalt my God, and my soul rejoices in the King of heaven. 8 Let all people speak of his majesty, and acknowledge him in Jerusalem.
Cyprian Treatises 11:15
For the God whom we serve is able to deliver us out of the furnace of burning fire; and He will deliver us from your hands, O king. And if not, be it known unto you, that we do not serve your gods, and we do not adore the golden image which you have set up. And Daniel, devoted to God, and filled with the Holy Spirit, exclaims and says: I worship nothing but the Lord my God, who founded the heaven and the earth. Tobias also, although under a royal and tyrannical slavery, yet in feeling and spirit free, maintains his confession to God, and sublimely announces both the divine power and majesty, saying: In the land of my captivity I confess to Him, and I show forth His power in a sinful nation. What, indeed, do we find in the Maccabees of seven brethren, equals alike in their lot of birth and virtues, filling up the number seven in the sacrament of a perfected completion? Seven brethren were thus associating in martyrdom.
Notes and References
"... Cyprian of Carthage’s (bishop of Carthage 248/49–258 CE) use of Tobit is even broader; Gamberoni speaks of more than a dozen quotations in Cyprian’s oeuvre. Cyprian uses the book, alongside other scriptural passages as a scriptural fundus of arguments regarding the “benefits of good works and mercy.” Cyprian thus treats Tobit clearly as scripture. He even introduces it as scriptura divina in his treatise on the Lord’s prayer. Tobit, however, is not just a source for general aspects of Christian piety: Tobit 4:11 and its claim for mercy becomes an important argument in the discussion regarding the treatment of the so-called lapsi, that is Christians who negated their belief during the persecution under Emperor Decius (249–251 ce). Cyprian is also the first author who is interested in the figure of Tobit as an example of the righteous sufferer and patience. De Mortalitate (Mort. 10) and De Bono Patientiae (Ptient. 18) put Tobit, his justice and mercy, his suffering, and his final fate alongside the figure of Job. Even if he does not make extensive use of Tobit, Origen describes the book of Tobit (alongside Esther, Judith, and the Wisdom of Solomon) as being an appropriate text for beginners (Homily in Numbers 27:1) and understands it as part of the canon (Or. 14,4: ἐνδιάθηκος) while his Jewish partners in discussion do not acknowledge it. He uses the book, for example, in his discussion of proper prayer and for his teaching about angels. The later aspect plays also an important role in the apocryphal Testament of Solomon (fourth century), according to which Solomon castigates the demon Asmodaeus in a way which is heavily influenced by the book of Tobit ..."
