(1.) Jerusalem shall be a cup of trembling to all that lay siege to it, v. 2. They promise themselves that it shall be to them a cup of wine, which they shall easily and with pleasure drink off, and they thirst for its spoils, nay, they thirst for its blood, as for such a cup; but it shall prove a cup of slumber, nay, a cup of poison, to them, which, when they take it into their hands, and think it is all their own, they shall not be able to drink off: the fumes of it shall give them enough. When the kings were assembled against her, and saw how God was known in her palaces for a refuge, they trembled and hasted away; fear took hold upon them, as we find, Ps. xlviii. 3-6. Thus Alexander the Great was struck with amazement when he met Jaddus the high priest, and was deterred thereby from offering any violence to Jerusalem. When Sennacherib laid siege against Judah and Jerusalem he found them such a cup of stupifying wine as laid all his mighty men asleep, Ps. lxxvi. 5, 6. Some read it, I will make Jerusalem a post of contrition or breaking. Those that make any attempts upon Jerusalem do but run their heads against a post, which they cannot move, but are sure to hurt themselves. The blast of the terrible ones is as a storm against the wall (Isa. xxv. 4), broken by it, but not shaking it. God's church is a cup of consolation to all her friends (Isa. lxvi. 11), but a cup of trembling to all that would either debauch her by errors and corruptions or destroy her by wars and persecutions. See Isa. li. 22, 23.
