2. He intimates to him whence the intended ruin should arise. Jeremiah is a second time asked: What seest thou? and he sees a seething-pot upon the fire (v. 13), representing Jerusalem and Judah in great commotion, like boiling water, by reason of the descent which the Chaldean army made upon them; made like a fiery oven (Ps. xxi. 9), all in a heat, wasting away as boiling water does and sensibly evaporating and growing less and less, ready to boil over, to be thrown out of their own city and land, as out of the pan into the fire, from bad to worse. Some think that those scoffers referred to this who said (Ezek. xi. 3), This city is the cauldron, and we are the flesh. Now the mouth or face of the furnace or hearth, over which this pot boiled, was towards the north, for thence the fire and the fuel were to come that must make the pot boil thus. So the vision is explained (v. 14): Out of the north an evil shall break forth, or shall be opened. It had been long designed by the justice of God, and long deserved by the sin of the people, and yet hitherto the divine patience had restrained it, and held it in, as it were; the enemies had intended it, and God had checked them; but now all restraints shall be taken off, and the evil shall break forth; the direful scene shall open, and the enemy shall come in like a flood. It shall be a universal calamity; it shall come upon all the inhabitants of the land, from the highest to the lowest, for they have all corrupted their way. Look for this storm to arise out of the north, whence fair weather usually comes, Job xxxvii. 22. When there was friendship between Hezekiah and the king of Babylon they promised themselves many advantages out of the north; but it proved quite otherwise: out of the north their trouble arose. Thence sometimes the fiercest tempests come whence we expected fair weather. This is further explained v. 15, where we may observe, (1.) The raising of the army that shall invade Judah and lay it waste: I will call all the families of the kingdoms of the north, saith the Lord. All the northern crowns shall unite under Nebuchadnezzar, and join with him in this expedition. They lie dispersed, but God, who has all men's hearts in his hand, will bring them together; they lie at a distance from Judah, but God, who directs all men's steps, will call them, and they shall come, though they be ever so far off. God's summons shall be obeyed; those whom he calls shall come. When he has work to do of any kind he will find instruments to do it, though he send to the utmost parts of the earth for them. And, that the armies brought into the field may be sufficiently numerous and strong, he will call not only the kingdoms of the north, but all the families of those kingdoms, into the service; not one able-bodied man shall be left behind. (2.) The advance of this army. The commanders of the troops of the several nations shall take their post in carrying on the siege of Jerusalem and the other cities of Judah. They shall set every one his throne, or seat. When a city is besieged we say, The enemy sits down before it. They shall encamp some at the entering of the gates, others against the walls round about, to cut off both the going out of the mouths and the coming in of the meat, and so to starve them.
