Proverbs 16:25 There is a way that seemeth right unto a man, but the end thereof are the ways of death.
[Patriarchs & Prophets pp 323] If Aaron had had courage to stand for the right, irrespective of consequences, he could have prevented that apostasy. If he had unswervingly maintained his own allegiance to God, if he had cited the people to the perils of Sinai, and had reminded them of their solemn covenant with God to obey His law, the evil would have been checked. But his compliance with the desires of the people and the calm assurance with which he proceeded to carry out their plans, emboldened them to go to greater lengths in sin than had before entered their minds.
When Moses, on returning to the camp, confronted the rebels, his severe rebukes and the indignation he displayed in breaking the sacred tables of the law were contrasted by the people with his brother's pleasant speech and dignified demeanor, and their sympathies were with Aaron. To justify himself, Aaron endeavored to make the people responsible for his weakness in yielding to their demand; but notwithstanding this, they were filled with admiration of his gentleness and patience.
But God seeth not as man sees. Aaron's yielding spirit and his desire to please had blinded his eyes to the enormity of the crime he was sanctioning. His course in giving his influence to sin in Israel cost the life of thousands. In what contrast with this was the course of Moses, who, while faithfully executing God's judgments, showed that the welfare of Israel was dearer to him than prosperity or honor or life.
Exodus 32:20 And he took the calf which they had made, and burnt it in the fire, and ground it to powder, and strawed it upon the water, and made the children of Israel drink of it.
May The Lord add His blessing to the study of His word. God bless!
