Tobit 4:10
5 "Revere the Lord all your days, my son, and refuse to sin or to transgress his commandments. Live uprightly all the days of your life, and do not walk in the ways of wrongdoing; 6 for those who act in accordance with truth will prosper in all their activities. To all those who practice righteousness 7 give alms from your possessions, and do not let your eye begrudge the gift when you make it. Do not turn your face away from anyone who is poor, and the face of God will not be turned away from you. 8 If you have many possessions, make your gift from them in proportion; if few, do not be afraid to give according to the little you have. 9 So you will be laying up a good treasure for yourself against the day of necessity. 10 For almsgiving delivers from death and keeps you from going into the Darkness. 11 Indeed, almsgiving, for all who practice it, is an excellent offering in the presence of the Most High.
Didache 4:5
3 Don't seek division but reconcile those in conflict. Make fair judgments; don't show favoritism when correcting wrongs. 4 Don't be double-minded about whether something should be or not. 5 Don't be someone who is eager to receive but reluctant to give. 6 Give a portion of what you've earned with your hands as a ransom for your sins. 7 Don't hesitate to give, nor complain when you do, for you'll know who rewards you well. 8 Don't turn away those in need, but share everything with your family, and don't claim it as your own. If you share in what is eternal, how much more should you share in what is perishable? 9 Don't withhold correction from your son or daughter, but teach them to respect God from a young age.

"... [Didache 4:5-8] Parallels: Doctr. 4:6 and Barnabas 19:10 in the final section. In Barnabas, however, the material assistance to the poor in atonement for one’s sins is considered as one of the options (the other is the ‘ministry of the word’) to which the members of the community are called to practice ... The expiatory value of charity is constant in both Hebrew literature and spirituality of ancient, middle and Rabbinical Judaism.
