Charles H. Spurgeon on Psalms 94:3

How long shall the wicked triumph? What answer shall we give, what date shall we put to this, "How long?" The answer is given in Ps 94:23, "He shall bring upon them their own iniquity, and shall cut them off in their own wickedness, "etc. As if he had said, Except the Lord cut them off in their wickedness, they will never leave off doing wickedly. They are men of such a kind that there is no curing of them, they will never have done doing mischief until they be cut off by death, therefore God threatens death to deter men from sin. A godly man saith, "If God kill me, yet will I trust in him; "and some wicked men say (in effect, if not in the letter), Till God kills us we will sin against him. Joseph Caryl.

Verses 3-4. Triumph, utter and speak, boast. In the very terms wherein the Psalmist complains of the continued prevalence of the wicked, there is matter of comfort, for we have three (rather four, as in the authorised version) words to denote speaking, and only one, workers, to denote action, showing us that they are far more powerful with their tongues than with their hands. Hugo Cardinalis, quoted by Neale.
