1, 2. Aaron‘s Sin, Pacifying—We repeat the sin of Aaron, pacifying, when the eyesight should be clear to discern evil and state it plainly, even if it places us in an unpleasant position, because our motives may be misapprehended. We must not suffer wrong upon a brother or any soul with whom we are connected. This neglect to stand up firmly for truth was the sin of Aaron. Had he spoken the truth plainly, that golden calf would never have been made. The same spirit that led him to shun to declare the whole truth for fear of offending, led him to act a falsehood in pointing to the golden calf as a representation of the One who brought them from Egypt. Thus one unfaithfulness leads to another (Letter 10, 1896).

4, 5. Idol Proclaimed God—The result of their murmuring and unbelief was that Aaron made them a golden calf to represent God. He proclaimed this idol to be God, and a great deal of enthusiasm was created over this false God (The Review and Herald, September 6, 1906).

19. Tables of Law Purposely Broken—In utter discouragement and wrath because of their great sin, he [Moses] threw down the tables of stone by divine direction purposely to break them in the sight of the people, and thus signify that they had broken the covenant so recently made with God (The Signs of the Times, May 20, 1880).
