In the NT it denotes "righteous," a state of being right, or right conduct, judged whether by the Divine standard, or according to human standards, of what is right. Said of God, it designates the perfect agreement between His nature and His acts (in which He is the standard for all men). See RIGHTEOUSNESS. It is used

(b) of Christ, e.g., Acts 3:14; Acts 7:52; Acts 22:14; 2 Timothy 4:8; 1 Peter 3:18; 1 John 2:1;
(c) of men, Matthew 1:19; Luke 1:6; Romans 1:17; Romans 2:13; Romans 5:7.

[ A-2,Adjective,G1738, endikos ]
"just, righteous" (en, "in," dike, "right"), is said of the condemnation of those who say "Let us do evil, that good may come," Romans 3:8; of the recompense of reward of transgressions under the Law, Hebrews 2:2.
Note: As to the distinction between No. 1 and No. 2, "dikaios characterizes the subject so far as he or it (so to speak) one with dike, right; endikos, so far as he occupies a due relation to dike; ... in Romans 3:8 endikos presuposes that which has been decided righteously, which leads to the just sentence" (Cremer).
