Exodus 32:5 And when Aaron saw it, he built an altar before it; and Aaron made proclamation, and said, Tomorrow is a feast to the Lord.
When Aaron observed the favor with which the calf was received, he became even more motivated to please and instead of putting on the brakes he went even further by announcing a grand festival in what he advertised as a feast to The Lord. Thus, he would blend the sacred and the common in order to please, not because it was right.
And as is too often the case, that grave pattern of conduct would be transferred genetically to Aaron’s sons, who later would be found mixing the sacred with the common, in so much that God had to visit them with judgments when they mingled drunkenness with the sacred service. Like every other characteristic, the disposition to appease and palliate, when firmness and principle are needed, is transferred from father to son as a legacy.
Therefore, the people, who now had the sanction of Aaron, would be all too eager to pull out all of the stops, for in their minds, if the spiritual leader is in agreement, and goes so far as to approve idolatry, and announce a grand festival in honor of the golden calf, when they didn’t ask for any celebration, then they would respond in the positive, and give vent to their latent desires, which sought an opportune moment to converge.
Exodus 32:And they rose up early on the morrow, and offered burnt offerings, and brought peace offerings; and the people sat down to eat and to drink, and rose up to play.
May God add His blessing to the study of His word. “Good night” and God bless!
