3. Let her know that God is displeased, highly displeased, at her wickedness, and does and will witness against it (v. 13): I have smitten my hand at thy dishonest gain. God, both by his prophets and by his providence, revealed his wrath from heaven against their ungodliness and unrighteousness, the oppressions they were guilty of, though they got by them, and their murders (the blood which has been in the midst of thee), and all their other sins. Note, God has sufficiently discovered how angry he is at the wicked courses of his people; and, that they may not say that they have not had fair warning, he smites his hand against the sin before he lays his hand upon the sinner. And this is a good reason why we should despise dishonest gain, even the gain of oppressions, and shake our hands from holding bribes, because these are sins against which God shakes his hands, Isa. xxxiii. 15.
