2 Enoch

Blessed is the man who in his patience brings his gifts with faith before the Lord �s face, because he will find forgiveness of sins.

But if he take back his words before the time, there is no repentance for him; and if the time pass and he do not of his own will what is promised, there is no repentance after death.

Because every work which man does before the time, is all deceit before men, and sin before God .
