1. The great wickedness that these heads of the house of Jacob were guilty of, princes, priest, and prophets; in short, they were covetous and prostituted their offices to their love of money. (1.) The princes abhorred all judgment; they would not be governed by any of its laws, either in their own practice or in passing sentence upon appeals made to them; they perverted all equity, and scorned to be under the direction or correction of justice, when it could not be made pliable to their secular interests. When, under pretence of doing right, they did the most palpable wrongs, then they perverted equity, and made it serve a purpose contrary to the intention of the founder of magistracy and fountain of power. It is laid to their charge (v. 10) that they build up Zion with blood. "They pretend, in justification of their extortion and oppressions, that they build up Zion and Jerusalem; they add new streets and squares to the holy cities, and adorn them; they establish and advance the public interests both in church and state, and think that therein they do God and Israel good service. But it is with blood and with iniquity, and therefore it cannot prosper; nor will their intentions of good to the city of God justify their contradictions to the law of God." Those mistake who think that a burning zeal for holy church, and the propagating of the faith, will serve to consecrate robberies and murders, massacres and depredations; no, Zion's walls owe those no thanks that build them up with blood and iniquity. The sin of man works not the righteousness of God. "The office of the princes is to judge upon appeals made to them; but they judge for reward (v. 11); they give judgment on the side of those that give the bribe; the most righteous cause shall not be carried without a fee, and for a fee the most unrighteous cause shall be carried." Miserable is the people's case when the judge's enquiry upon a cause is not, "What is to be done in it?" but, "What is to be got by it?" (2.) The priests' work was to teach the people, and for that the law had provided them a very honourable comfortable maintenance; but that will not content them, they teach for hire over and above, and will be hired to teach anything, as an oracle of God, which they know will please and gain them an interest. (3.) The prophets, it should seem, had honorary fees given them by way of gratuity (1 Sam. ix. 7, 8); but these prophets governed themselves in their prophesying by the prospect of temporal advantage and that was the main thing they had in their eye: They divine for money. Their tongues were mercenary; they would either prophesy or let it alone, according as they found it most for their advantage; and a man might have what oracle he would from them if he would but pay them for it. Thus they were fit successors of Balaam, who loved the wages of unrighteousness. Note, Though that which is wicked can never be consecrated by a zeal for the church, yet that which is sacred may be, and often is, desecrated, by the love of the world. When men do that which in itself is good, but do it for filthy lucre, it loses its excellency, and becomes an abomination both to God and man.
