Psalms 106:21

Those that will not wait for God's counsel, shall justly be given up to their own hearts' lusts, to walk in their own counsels. An undue desire, even for lawful things, becomes sinful. God showed his displeasure for this. He filled them with uneasiness of mind, terror of conscience, and self-reproach. Many that fare deliciously every day, and whose bodies are healthful, have leanness in their souls: no love to God, no thankfulness, no appetite for the Bread of life, and then the soul must be lean. Those wretchedly forget themselves, that feast their bodies and starve their souls. Even the true believer will see abundant cause to say, It is of the Lord's mercies that I am not consumed. Often have we set up idols in our hearts, cleaved to some forbidden object; so that if a greater than Moses had not stood to turn away the anger of the Lord, we should have been destroyed. If God dealt severely with Moses for unadvised words, what do those deserve who speak many proud and wicked words? It is just in God to remove those relations that are blessings to us, when we are peevish and provoking to them, and grieve their spirits.

They forgat God their saviour. Remembering the calf involved forgetting God. He had commanded them to make no image, and in daring to disobey they forgot his commands. Moreover, it is clear that they must altogether have forgotten the nature and character of Jehovah, or they could never have likened him to a grass eating animal. Some men hope to keep their sins and their God too —the fact being that he who sins is already so far departed from the Lord that he has actually forgotten him. Which had done great things in Egypt. God in Egypt had overcome all the idols, and yet they so far forgot him as to liken him to them. Could an ox work miracles? Could a golden calf cast plagues upon Israel's enemies? They were brutish to set up such a wretched mockery of deity, after having seen what the true God could really achieve. "Wondrous works in the land of Ham, and terrible things by the Red sea". They saw several ranges of miracles, the Lord did not stint them as to the evidences of his eternal power and godhead, and yet they could not rest content with worshipping him in his own appointed way, but must needs have a Directory of their own invention, an elaborate ritual after the old Egyptian fashion, and a manifest object of worship to assist them in adoring Jehovah. This was enough to provoke the Lord, and it did so; how much he is angered every day in our own land no tongue can tell.
