Charles H. Spurgeon on Psalms 106:29

Their inventions. Their sins are here called by the name of "their inventions." And so, sure, they are; as no ways taught us by God, but of our own imagining or finding out. For, indeed, our inventions are the cause of all sins. And if we look well into it we shall find our inventions are so. By God's injunction we should all live, and his injunction is, "You shall not do every man what seems good in his own eyes" (or finds out in his own brains), but "whatsoever I command you, that shall you do." De 12:8. But we, setting light by that charge of his, out of the old disease of our father Adam ("ye shall be as gods, knowing good and evil"), think it a goodly matter to be witty, and to find out things ourselves to make to ourselves, to be authors, and inventors of somewhat, that so we may seem to be as wise as God, if not wiser; and to know what is for our turns, as well as he, if not better. It was Saul's fault. God bade him destroy Amalek altogether, and he would invent a better way, to save some (forsooth) for sacrifice, which God could not think of. And it was St. Peter's fault, when he persuaded Christ from his passion, and found out a better way (as he thought) than Christ could devise. Lancelot Andrewes.
