Isaiah 1:12

12.Who hath required this at your hand ? What an admirable confutation of false worship, when God declares that they will not come before him according to the appointed manner, and makes a general declaration, that in vain do they offer to him anything which he does not require; for he does not choose to be worshipped in any other way than that which has been enjoined! For how comes it that men are so highly delighted with those inventions, but because they do not consider that all their services are neither profitable to themselves nor acceptable to God? Otherwise they would immediately recollect that obedience is all that remains for them to do; (1 Samuel 15:22;) and they would not so insolently vaunt of their exertions, which the Lord looks upon with scorn, not only because he derives no advantage from it, but because he does not wish that men should attribute to him what they have rashly undertaken without his authority, or suffer the caprice of men to pass for a law: Yet in order to express still stronger contempt, he immediately adds, that they improperly give the name of obedience to that which he considers to be labor thrown away; namely, that their close attendance at the temple amounts to nothing more than treading its pavements; as if, in reference to their hypocritical prayers, he had said, “Truly they lay me under deep obligations by stunning my ears.”
