And burn incense with the leaven of thank offering He speaks of peace-offerings; sacrifices of thanksgiving were wont to be offered with leaven; but with other sacrifices they presented cakes and unleavened bread. It was lawful in peace-offerings to offer leaven. However sedulous, then, the Israelites were in performing these rites, the Prophet intimates that they were in no way approved by God inasmuch as they had departed from the pure command of the law. Some take leaven in a bad sense, as meaning a vicious and impure sacrifice, which the law required to be free from leaven; but this view seems not suitable here; for nothing is here condemned in the Israelites, but that they had departed from what the law prescribed, that they had presumptuously changed the place of the temple, and also raised up a new priesthood. They were in other things careful and diligent enough; but this defection was the chief abomination. It could not then be, that God would approve of deprivations; for obedience, as it is said elsewhere, is of more account before him than all sacrifices, (1 Samuel 15:22) Proclaim, he says, נדבות, nudabut, voluntary oblations. What he means is, “Though ye not only offer sacrifices morning and evenings as it has been commanded you, though ye not only present other sacrifices on festivals, but also add voluntary oblations to any extent, yet nothing pleases me.”
Bring forth then, and proclaim voluntary offerings; that is, “Appoint solemn assemblies with great pomp; yet this would be nothing else than to add sin to sin: ye are acting wickedly for this reason, — because the very beginning is impious.”
But the last part of the verse must be noticed, For so it has pleased you, O children of Israel, saith the Lord Jehovah. By saying that the Israelites loved to do these things, he reprobates their presumption in devising at their own will new modes of worship; as though he said, “I require no sacrifices from you except those offered at Jerusalem; but ye offer them to me in a profane place. Regard then your sacrifices as offered to yourselves, and not to me.” We indeed know how hypocrites ever make God a debtor to themselves; when they undertake any labor in their frivolous ceremonies, they think that God is bound to them. But God denies that this work was done for him, for he had not enjoined it in his law. “It has thus pleased you,” he says, “ Vous faites cela pour votre plaisir et bien mettez le sur vos comptes “. We then see what Amos meant here by saying, ‘It has so pleased you, O children of Israel:’ it is, as if he had said, “Ye ought to have consulted me, and simply to have obeyed my word, to have regarded what pleased me, what I have commanded; but ye have despised my word, neglected my law, and followed what pleased yourselves, and proceeded from your own fancies. Since, then, your own will is your law, seek a recompense from yourselves, for I allow none of these things. What I require is implicit submission, I look for nothing else but obedience to my law; as ye render not this but according to your own will, it is no worship of my name.”
