Leviticus 26:25

25. Avenge the quarrel of my covenant Literally, avenging the covenant of vengeance. The R.V., “Execute the vengeance of the covenant.” This was a punishment inflicted for breaking the covenant, and it was graduated, in severity, to the richness of covenant blessings forfeited by apostasy. “It may be reverently said that God does not deal carelessly with his own covenants. He does not throw them away, and take no further heed of their operation. In the sense of looking after his word and observing its issues he may be described in Old Testament language as a ‘jealous God.’” Joseph Parker. The Abrahamic covenant is here personified as a friend of God claiming vindication against the neglect and abuse of godless men. Sin changes the covenant of grace into the covenant of vengeance, and the love of the Saviour into “the wrath of the Lamb.” Revelation 6:16.
