I. Here is a word spoken against Babylon by him whose works all agree with his word and none of whose words fall to the ground. The king of Babylon had been very kind of Jeremiah, and yet he must foretel the ruin of that kingdom; for God's prophets must not be governed by favour or affection. Whoever are our friends, if, notwithstanding, they are God's enemies, we dare not speak peace to them. 1. The destruction of Babylon is here spoken of as a thing done, v. 2. let it be published to the nations as a piece of news, true news, and great news, and news they are all concerned in; let them hang out the flag, as is usual on days of triumph, to give notice of it; let all the world take notice of it: Babylon is taken. Let God have the honour of it, let his people have the comfort of it, and therefore do not conceal it. Take care that it be known, that the Lord may be known by those judgments which he executes, Ps. ix. 16. 2. It is spoken of as a thing done thoroughly. For, (1.) The very idols of Babylon, which the people would protect with all possible care, and from which they expected protection, shall be destroyed. Bel and Merodach were their two principal deities; they shall be confounded, and the images of them broken to pieces. (2.) The country shall be laid waste (v. 3) out of the north, from Media, which lay north of Babylon, and from Assyria, through which Cyrus made his descent upon Babylon; thence the nation shall come that shall make her land desolate. Their land was north of the countries that they destroyed, who were therefore threatened with evil from the north (Omne malum ab aquilone—Every evil comes from the north); but God will find out nations yet further north to come upon them. The pomp and power of old Rome were brought down by northern nations, the Goths and Vandals.
