Tobit 14:8
7 and in righteousness they will praise the eternal God. All the Israelites who are saved in those days and are truly mindful of God will be gathered together; they will go to Jerusalem and live in safety forever in the land of Abraham, and it will be given over to them. Those who sincerely love God will rejoice, but those who commit sin and injustice will vanish from all the earth. 8 So now, my children, I command you, serve God faithfully and do what is pleasing in his sight. Your children are also to be commanded to do what is right and to give alms, and to be mindful of God and to bless his name at all times with sincerity and with all their strength. So now, my son, leave Nineveh; do not remain here. 10 On whatever day you bury your mother beside me, do not stay overnight within the confines of the city. For I see that there is much wickedness within it, and that much deceit is practiced within it, while the people are without shame. See, my son, what Nadab did to Ahikar who had reared him. Was he not, while still alive, brought down into the earth? For God repaid him to his face for this shameful treatment. Ahikar came out into the light, but Nadab went into the eternal darkness, because he tried to kill Ahikar. Because he gave alms, Ahikar escaped the fatal trap that Nadab had set for him, but Nadab fell into it himself, and was destroyed.
Cyprian Treatises 8:20
20 Be rather such a father to your children as was Tobias. Give useful and saving precepts to your pledges, such as he gave to his son; command your children what he also commanded his son, saying: And now, my son, I command you, serve God in truth, and do before Him that which pleases Him; and command your sons, that they exercise righteousness and alms, and be mindful of God, and bless His name always. And again: All the days of your life, most dear son, have God in your mind, and be not willing to transgress His commandments. Do righteousness all the days of your life, and be not willing to walk in the way of iniquity; because if you deal truly, there will be respect of your works. Give alms of your substance, and turn not away your face from any poor man. So shall it be, that neither shall the face of God be turned away from you. As you have, my son, so do. If your substance is abundant, give alms of it the more. If you have little, communicate of that little. And fear not when you do alms; for you lay up a good reward for yourself against the day of necessity, because that alms do deliver from death, and suffers not to come into Gehenna. Alms is a good gift to all that give it, in the sight of the most high God.
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 ..."
