1 Enoch 91:4
3 And he spake unto all the children of righteousness and said: 'Hear, ye sons of Enoch, all the words of your father, And hearken aright to the voice of my mouth; For I exhort you and say unto you, beloved: Love uprightness and walk therein. 4 And draw not nigh to uprightness with a double heart, And associate not with those of a double heart, But walk in righteousness, my sons. And it shall guide you on good paths, And righteousness shall be your companion. 5 For I know that violence must increase on the earth, And a great chastisement be executed on the earth, And all unrighteousness come to an end: Yea, it shall be cut off from its roots, And its whole structure be destroyed.
Didache 4:4
2 And thou shalt seek daily the presence of the saints, that thou mayest find rest in their words. 3 Thou shalt not desire a schism, but shalt reconcile those that strive. Thou shalt give righteous judgement; thou shalt favor no mans person in reproving transgression. 4 Thou shalt not be of two minds whether it shall be or not. 5 Be not one who stretches out his hands to receive, but shuts them when it comes to giving. 6 Of whatsoever thou hast gained by thy hands thou shalt give a ransom for thy sins.
Notes and References
"... While the second instance, which brands “those of double heart” as a group, does not allow for ambiguity that conceives of them doing good as well as bad, the first occurence holds open the possibility that anyone, perhaps even the righteous, might be subject to the “double heart”, and so warns them away. This point cannot, in the end, be pressed too far. The remaining emphasis on “two ways” throughout chapters 91–105 distinguishes the righteous and sinners or oppressors as social groups to such a degree that it is more likely that the righteous are simply being warned away from getting into a state of dividedness (i.e. sinfulness) to begin with.333
333 A similar use of the motif of “double-mindedness” occurs within the “two ways” instruction in Did. 1:1–6:3; see esp. 2:4 and 4:4.
