Sirach 4:31
Ben Sira, Ecclesiasticus25 Never speak against the truth, but be ashamed of your ignorance. 26 Do not be ashamed to confess your sins, and do not try to stop the current of a river. 27 Do not subject yourself to a fool, or show partiality to a ruler. 28 Fight to the death for truth, and the Lord God will fight for you. 29 Do not be reckless in your speech, or sluggish and remiss in your deeds. 30 Do not be like a lion in your home, or suspicious of your servants. 31 Do not let your hand be stretched out to receive and closed when it is time to give.
Barnabas 19:9
Epistle of Barnabas8 Thou shalt make thy neighbor partake in all things, and shalt not say that anything is thine own. For if ye are fellow partakers in that which is imperishable, how much rather shall ye be in the things which are perishable. Thou shalt not be hasty with thine own tongue, for the mouth is the snare of death. So far as thou art able, thou shalt be pure for thy soul's sake. 9 Be not thou found holding out thy hands to receive, and drawing them in to give. Thou shalt love as the apple of thine eye everyone that speaketh unto thee the word of the Lord. 10 Thou shalt remember the day of judgment night and day, and thou shalt seek out day by day the persons of the saints, either laboring by word and going to exhort them and meditating how thou mayest save souls by thy word, or thou shalt work with thy hands for a ransom for thy sins.
Notes and References
"... The book of Sirach is not quoted directly in the New Testament. The strongest parallel is Matthew 11:28-30 (= Sirach 6:24-25; 51:26-27). But even there it may be a matter of common terminology and conceptuality. Yet Sirach is a precious resource for understanding the presuppositions of Judaism in the late Second Temple period and for discerning what was or was not innovative about Jesus and early Christianity. The earliest patristic evidence for Sirach occurs in Didache 4:5 and Barnabas 19:9, which appear to cite Sirach 4:31. The book was translated into Larin, Coptic, Syriac, Ethiopic, Armenian, and Arabic, thus insuring a wide circulation. Many Greek church fathers (Clement of Alexandria, Origen, John Chrysostom, Cyril of Jerusalem) and Latin fathers (Tertullian, Cyprian, Jerome, Augustine) quoted or incorporated material from Sirach in their own works. Throughout the late patristic and medieval periods, Sirach generated a rich commentary tradition ..."
