dikaios describes persons marked as righteous or just, and judgments or actions assessed as right and fair.

The dominant use characterizes people as righteous or just, whether their conduct, standing before God, prayer, or treatment is in view. It also describes judgments, decisions, repayment, and provision as right, just, or fair.

1. Persons characterized as righteous or just · dominant

   The nominative plural form in Luke 1:6 characterizes two people who walk in the Lord's commandments and righteous acts, while the genitive singular in James 5:16 occurs in the clause about a righteous person's effective petition. In 1 Peter 3:18 the nominative singular stands in the contrast of the just for the unjust, and Acts 3:14 uses the accusative singular in the designation “the holy and just one.”

2. What is right or fair in judgment and action · common

   The neuter singular form occurs where a course of action or provision is assessed: in Ephesians 6:1 the APB renders the clause about children obeying their parents, “for this is just,” and in Colossians 4:1 masters are told to provide what is “just and fair.” The feminine singular form in John 5:30 occurs in the statement that a judgment is just, while 2 Thessalonians 1:6 calls repayment by God just.

In the Anselm Project Bible: Across the supplied verses, the APB uses “righteous” and “just” for people, and “just,” “right,” and “fair” in clauses about judgments, conduct, repayment, and provision. These renderings confirm the clauses' overall presentation rather than fixing a separate English equivalent in every instance.
