Apostolic Fathers
I asked him again, and said, “Since the Lord has vouchsafed to dwell always with me, bear with me while I utter a few words; for I understand nothing, and my heart has been hardened by my previous mode of life. Give me understanding, for I am exceedingly dull, and I understand absolutely nothing.” And he answered and said unto me, “I am set over repentance, and I give understanding to all who repent. Do you not think,” he said, “that it is great wisdom to repent? for repentance is great wisdom. For he who has sinned understands that he acted wickedly in the sight of the Lord, and remembers the actions he has done, and he repents, and no longer acts wickedly, but does good munificently, and humbles and torments his soul because he has sinned. You see, therefore, that repentance is great wisdom.” And I said to him, “It is for this reason, sir, that I inquire carefully into all things, especially because I am a sinner; that I may know what works I should do, that I may live: for my sins are many and various.” And he said to me, “You shall live if you keep my commandments, and walk in them; and whosoever shall hear and keep these commandments, shall live to God.”
Jubilees
unto him: 'Let me not be bereft of both my sons on one day.' And Jacob said to Rebecca his mother: 'Behold, thou knowest that my father has become old, and does not see because his eyes are dull, and if I leave him it will be evil in his eyes, because I leave him and go away from you, and my father will be angry, and will curse me. I will not go; when he sends me, then only will I go.'
OT Pseudepigrapha
And the Lord appointed him ruler over all, and subjected to him all things under his hands, and made them dumb and made them dull that they be commanded of man, and be in subjection and obedience to him.
