Vengeance - Vine's Expository Dictionary of New Testament Words
Vengeance[ 1,,G1557, ekdikesis ]
lit., (that which proceeds) out of justice," not, as often with human "vengeance," out of a sense of injury or merely out of a feeling of indignation. The word is most frequently used of Divine "vengeance," e.g., Romans 12:19; Hebrews 10:30. For a complete list See AVENGE, B, No. 2. The judgements of God are holy and right (Revelation 16:7), and free from any element of self-gratification or vindictiveness.
(1) Dike, "justice," is translated "vengeance" in the AV of Acts 28:4 and Jude 1:7, See JUSTICE.
(2) In Romans 3:5, AV, orge, "wrath" (RV), is rendered "vengeance;" See ANGER, WRATH.
