I. The prophet had foreseen the prevalence of the church's enemies and the long continuance of the church's troubles; and the sight made him tremble, v. 16. Here he goes on with what he had said v. 2, "I have heard thy speech and was afraid. When I heard what sad times were coming upon the church my belly trembled, my lips quivered at the voice; the news made such an impression that it put me into a perfect ague fit." The blood retiring to the heart, to succour that when it was ready to faint, the extreme parts were left destitute of spirits, so that his lips quivered. Nay, he was so weak, and so unable to help himself, that he was as if rottenness had entered into his bones; he had no strength left in him, could neither stand nor go; he trembled in himself, trembled all over him, trembled within him; he yielded to his trembling, and troubled himself, as our Savior did; his flesh trembled for fear of God and he was afraid of his judgments, Ps. cxix. 120. He was touched with a tender concern for the calamities of the church, and trembled for fear lest they should end at length in ruin, and the name of Israel be blotted out. Nor did he think it any disparagement to him, nor any reproach to his courage, but freely owned he was one of those that trembled at God's word, for to them he will look with favour: I tremble in myself, that I might rest in the day of trouble. Note, When we see a day of trouble approaching it concerns us to provide accordingly, and to lay up something in store, by the help of which we may rest in that day; and the best way to make sure rest for ourselves in the day of trouble is to tremble within ourselves at the word of God and the threatenings of that word. He that has joy in store for those that sow in tears has rest in store for those that tremble before him. Good hope through grace is founded in a holy fear. Noah, who was moved with fear, trembled within himself at the warning given him of the deluge coming, had the ark for his resting place in the day of that trouble. The prophet tells us what he said in his trembling. His fear is that, when he comes up to the people, when the Chaldean comes up to the people of Israel, he will invade them, will surround them, will break in upon them, nay (as it is in the margin), He will cut them in pieces with his troops; he cried out, We are all undone; the whole nation of the Jews is lost and gone. Note, When things look bad we are too apt to aggravate them, and make the worst of them.
