• Strong's:
  adikia, ad-ee-kee'-ah; from Adikos (94).
  (Legal) injustice (properly the quality, by implication the act); moral wrongfulness (of character, life or act). KJV "iniquity, unjust, unrighteousness, wrong".
• Zodhiates:
  CHAIro-; genitive adiKIas, feminine noun from Adikos (94), unjust.
  Injustice. What is not conformable with justice, what ought not to be, that which is wrong. Related to Adikos, unjust, that which is out of harmony with DIke-, established usage, what is right and fit, hence injustice, unrighteousness. There is adiKIa only because there is aLE-theia (225), truth, which occupies the place of DIke-, justice. The result of adiKIa is aDIke-ma (92), evil doing. (1 John 3:4; 5:17; Acts 18:14)
  1. Wrong, injustice.
     1. Generally. (Luke 18:6; Rom. 9:14; LXX Deut. 32:4)
     2. Wrong or injury as done to others. (2 Cor. 12:13; LXX Ps. 7:3; Mic. 3:10)
  2. As related to dikaioSYne- (1343), righteousness which is often used of life and conduct. Thus adiKIa takes by antithesis the sense of impropriety, iniquity, unrighteousness, wickedness. (Luke 13:27; Acts 1:18; Rom. 1:29; 1 John 5:17)
  3. Fraud, deceit, guile. (John 7:18)
  4. Money, as in the context of the parable of Luke 16:1-9. In verse 8, it stands for money as leading to unrighteousness. In this verse, the "steward of unrighteousness [author's translation]" should be understood as the steward of money since he was entrusted with the handling of the rich man's money and apparently did nothing wrong in collecting at a discount rate bad debts which were owed to his master.
     • In Acts 8:23, Peter was speaking to Simon the sorcerer, and said to him, "For I perceive that thou art in the gall of bitterness, and in the bond of iniquity [adiKIas]."
     • 1 Cor. 13:6 could be taken as those material things that could be acquired through the employment of falsehood in defrauding others instead of telling the truth.
     • In Hos. 12:7, the word "deceit" (4820, OT) means ill-gotten wealth and is translated in the LXX as adiKIa.
     • See also Ezek. 28:18, "the iniquity of thy traffic" which means making money through false merchandising.
     • See also Deut. 19:18; Mic. 6:12.
• Mounce:
  GK 94 (S 93) Word occurs 25 times. adikia is consistently translated as either "unrighteousness" or "iniquity" in the KJV. The NIV, however, offers numerous glosses, such as
  • Evil. (James 3:6, the tongue is "a world of evil")
  • Wickedness. (Rom. 6:13)
  • Dishonest. (Luke 16:8)
  • Worldly. (Luke 16:9)
  • Sin. (Acts 8:23)
  • Wrong. (2 Cor. 12:13)
  • Wrongdoing. (1 John 5:17, which unequivocally declares, "All wrongdoing is sin")
  adikia specifically denotes anything that is incongruous with divine or human law, i.e., what is just or righteous.
  • Paul declares that "the wrath of God is being revealed from heaven against all the godlessness and wickedness of men". (Rom. 1:18)
  • And that "all will be condemned who have not believed the truth but have delighted in wickedness." (2 Thess. 2:12)
  • Paul defends his conviction of the righteous judgment of God when rhetorically he asks, "If our unrighteousness brings out God's righteousness more clearly, what shall we say? That God is unjust in bringing his wrath on us?" (Rom. 3:5, cf. 9:14)
  • Absolutely not, for God is a righteous judge and is just in all of his dealings toward us. (Rom. 3:5, Heb. 6:10)
  • In light of impending wrath and judgment against adikia, Paul charged the Romans: "Do not offer the parts of your body to sin, as instruments of wickedness, but rather offer yourselves to God, as those who have been brought from death to life." (Rom 6:13)
  • Paul's rationale for this appeal is rooted in the nature and evidences of salvation, "Everyone who confesses the name of the LORD must turn away from wickedness". (2 Tim. 2:19)
  • Nonetheless, on those occasions when we do commit adikia, "if we confess our sins, he [God] is faithful and just and will forgive us our sins and purify us from all unrighteousness." (1 John 1:9; cf. Heb. 8:12)
• Vine's:
  • Iniquity, No. 2, denotes unrighteousness, literally, 'unrightness' (a, negative, dike-, right), a condition of not being right, whether with God, according to the standard of His holiness and righteousness, or with man, according to the standard of what man knows to be right by his conscience. In Luke 16:8 and 18:6, the phrases literally are, 'the steward of unrighteousness' and 'the judge of injustice', the subjective genitive describing their character; in 18:6 the meaning is 'injustice' and so perhaps in Rom. 9:14. The word is usually translated 'unrighteousness', but is rendered 'iniquity' in Luke 13:27; Acts 1:18; 8:23; 1 Cor. 13:6, AV, (RV 'unrighteousness'); so in 2 Tim. 2:19; Jas. 3:6.
  • Unrighteousness, No. 1, denotes
    1. Injustice.
       • Luke 18:6, literally, 'the judge of injustice'.

       • Rom. 1:18, 29; 2:8; 3:5; 6:13.
       • 1 Cor. 13:6, RV, 'unrighteousness'.
       • 2 Thess. 2:10, '[with all (literally, in every) deceit] of unrighteousness', i.e., deceit such as unrighteousness uses, and that in every variety. Antichrist and his ministers will not be restrained by any scruple from words or deeds calculated to deceive.
       • 2 Thess. 2:12, of those who have pleasure in it, not an intellectual but a moral evil. Distaste for truth is the precursor of the rejection of it.
       • 2 Tim. 2:19, RV; 1 John 1:9.
    3. A deed or deeds violating law and justice (virtually the same as adike-ma, an unrighteous act).
       • Luke 13:27, 'iniquity'.
       • 2 Cor. 12:13, 'wrong', the wrong of depriving another of what is his own, here ironically of a favor.
       • Heb. 8:12, first clause, 'iniquities', literally, 'unrighteousnesses' (plural, not as AV).
       • 2 Pet. 2:13, 15, RV, 'wrong doing', AV, 'unrighteousness'.
       • 1 John 5:17.
  • Notes:
    1. In 2 Cor. 6:14, AV, anomia, lawlessness, is translated 'unrighteousness' (RV, 'iniquity').
    2. adikia is the comprehensive term for wrong, or wrong-doing, as between persons; anomia, lawlessness, is the rejection of Divine law, or wrong committed against it.
