Charles Ellicott Commentary Malachi 2:17

"Ye have wearied Jehovah with your words. Yet ye say, Wherein have we wearied him? In that ye say, Every one that doeth evil is good in the sight of Jehovah, and he delighteth in them; or where is the God of justice?" — Malachi 2:17 (ASV)

REBUKE OF INFIDELITY. THE ADVENT OF THE LORD FORETOLD (Malachi 2:17 to Malachi 3:18).

A new section of the prophecy begins with this verse. The prophet now directs his reproofs against the people for their discontent and their lack of faith in God's promises, because the expected manifestation of God’s glory did not take place immediately. Because the doers of evil seem to flourish, the people say that God takes delight in them; or—that is, if this is not the case—“Where is the God of judgment?” since He does not intervene to punish them. (Compare to Psalm 73:1 and following)
