Wisdom of Solomon 12:10
8 But even these you spared, since they were but mortals, and sent wasps as forerunners of your army to destroy them little by little, 9 though you were not unable to give the ungodly into the hands of the righteous in battle, or to destroy them at one blow by dread wild animals or your stern word. 10 But judging them little by little you gave them an opportunity to repent, though you were not unaware that their origin was evil and their wickedness inborn, and that their way of thinking would never change. 11 For they were an accursed race from the beginning, and it was not through fear of anyone that you left them unpunished for their sins.
1 Clement 7:5
First Epistle of Clement to the Corinthians4 Let us fix our eyes on the blood of Christ and understand how precious it is to His Father, for by being shed for our salvation, it won for the whole world the grace of repentance. 5 Let us look back at all the generations in turn and learn how, from age to age, the Master has given a place for repentance to those who desire to turn to Him. 6 Noah preached repentance, and those who obeyed were saved. 7 Jonah preached destruction to the people of Nineveh, but they repented of their sins, obtained pardon from God through their supplications, and received salvation, even though they were strangers to Him.
Notes and References
"... The Apostolic Fathers (ca. 90-150 CE), those writings closest in chronology to the New Testament writings, have a number of even more striking parallels. quotations, and allusions to noncanonical literature. Notice, for example. that Clement of Rome (ca. 90-95 CE) cited Sirach 2:11 in 1 Clement 60.1, Wisdom of Solomon 12:10 in 1 Clement 7.5, and Wisdom of Solomon 12:12 in 1 Clement 27.5 (perhaps also alluded to in 3.4 and 7.5). In 1 Clement 55.4 6 both Judith (8ff.) and Esther (7 and 4:16) are cited authoritatively or scripturally. The author of 2 Clement (ca. 150 CE) has a number of quotations, allusions, and references from unknown and nonbiblical sources (see 11.2-4,7, and 13.2) as well as a quote from Tobit 16:4. Barnabas (ca. 90-130) employs quotations from Wisdom of Solomon (20.2), 1 Enoch (16.5), 4 Ezra (12.1), and from unknown 'scripture' as in 7.3, 8, and 10.7. The Didache (ca. 70-90 CE) makes use of Wisdom of Solomon in 5.2 and 10.3 as well as an unknown quote in 1.6. Polycarp cites Tobit 4:10 (see also 12:9) in Martyrdom 10.2 ..."
