If we do not keep God's commandments, we not only come short of the blessing promised, but we lay ourselves under the curse, which is as comprehensive of all misery as the blessing is of all happiness. Observe,

​

• I. The equity of this curse. It is not a curse causeless, nor for some light cause; God seeks not occasion against us, nor is he apt to quarrel with us. That which is here mentioned as bringing the curse is,

​

Despising God, refusing to hearken to his voice (v. 15), which bespeaks the highest contempt imaginable, as if what he said were not worth the heeding, or we were not under any obligation to him.

​

• 2. Disobeying him, not doing his commandments, or not observing to do them. None fall under his curse but those that rebel against his command.

​

• 3. Deserting him. "It is because of the wickedness of thy doings, not only whereby thou hast slighted me, but whereby thou hast forsaken me,' v. 20. God never casts us off till we first cast him off. It intimates that their idolatry, by which they forsook the true God for false gods, would be their destroying sin more than any other.

​

• II. The extent and efficacy of this curse.

​​

​In general, it is declared, "All these curses shall come upon thee from above, and shall overtake thee; though thou endeavour to escape them, it is to no purpose to attempt it, they shall follow thee whithersoever thou goest, and seize thee, overtake thee, and overcome thee,' v. 15. It is said of the sinner, when God's wrath is in pursuit of him, that he would fain flee out of his hand (Job 27:22), but he cannot; if he flee from the iron weapon, yet the bow of steel shall reach him and strike him through. There is no running from God but by running to him, no fleeing from his justice but by fleeing to his mercy. See Ps. 21:7, 8.

 

​​

• (1.) Wherever the sinner goes, the curse of God follows him; wherever he is, it rests upon him. He is cursed in the city and in the field, v. 16. The strength of the city cannot shelter him from it, the pleasant air of the country is no fence against these pestilential steams. He is cursed (v. 19) when he comes in, for the curse is upon the house of the wicked(Prov. 3:33), and he is cursed when he goes out, for he cannot leave that curse behind him, nor get rid of it, which has entered into his bowels like water and like oil into his bones.

​

• (2.). Whatever he has is under a curse: Cursed is the ground for his sake, and all that is on it, or comes out of it, and so he is cursed from the ground, as Cain, Gen. 4:11. The basket and store are cursed, v. 17, 18. All his enjoyments being forfeited by him are in a manner forbidden to him, as cursed things, which he has no title to. To those whose mind and conscience are defiled every thing else is so, Tit. 1:15. They are all embittered to him; he cannot take any true comfort in them, for the wrath of God mixes itself with them, and he is so far from having any security of the continuance of them that, if his eyes be open, he may see them all condemned and ready to be confiscated, and with them all his joys and all his hopes gone for ever.

​​

• (3.) Whatever he does is under a curse too. It is a curse in all that he sets his hand to (v. 20), a constant disappointment, which those are subject to that set their hearts upon the world, and expect their happiness in it, and which cannot but be a constant vexation. This curse is just the reverse of the blessing in the former part of the chapter. Thus whatever bliss there is in heaven there is not only the want of it, but the contrary to it, in hell. Isa. 65:13, My servants shall eat, but you shall be hungry.
