LXX Proverbs 1:4
3 and to receive subtlety of words, and to understand true righteousness, and to direct a judgment, 4 so that it may give cunning to the naive and both experience and insight to a young child. 5 For when the wise hears these things, he will become wiser, and the thoughtful will gain skill in navigation,
Ephesians 4:14
13 until we all attain to the unity of the faith and of the knowledge of the Son of God—a mature person, attaining to the measure of Christ’s full stature. 14 So we are no longer to be children, tossed back and forth by waves and carried about by every wind of teaching by the trickery of people who craftily carry out their deceitful schemes. 15 But practicing the truth in love, we will in all things grow up into Christ, who is the head.
Notes and References
"... LXX Proverbs 1:4 ... ἵνα δῷ ἀκάκοις πανουργίαν, “in order that he may impart shrewdness to the guileless.” In general Greek usage the word πανουργία, as well as the related adjective πανοῦργος, has a negative connotation, suggesting dishonest slyness and cunning. This is also true of biblical Greek outside of the book of Proverbs (see for example Numbers 24:22; Sirach 19:23; Luke 20:23; Ephesians 4:14). It is a peculiarity of the Greek of Proverbs, however, that it uses these words in a positive sense, suggesting godly wisdom. This positive connotation is clearly illustrated for πανουργία in the present verse (see also 8:5), and for πανοῦργος in the thirteen places where it occurs elsewhere in Proverbs ..."
