This chapter begins with the title of the book, showing the subject matter of it; and describing the penman of it by his name and country, Nah 1:1; which is followed with a preface to the whole book; setting forth the majesty of a jealous and revenging God; the power of his wrath and fury; of which instances are given in exciting tempests; drying up the sea and the rivers; making the most fruitful mountains barren, which tremble before him; yea, even the whole world, and the inhabitants thereof, his indignation being intolerable; and yet he is slow to anger, good to them that trust in him, whom he knows, and whose protection he is in a time of trouble, Nah 1:2. Next the destruction of the Assyrian empire, and of the city of Nineveh, is prophesied of; and is represented as an utter and an entire destruction, and which would come upon them suddenly and unawares, while they were in their cups, Nah 1:8. A particular person among them is spoken of, described as a designing wicked man, an enemy to the Lord and his people, thought to be Sennacherib king of Assyria, Nah 1:11; from whose evil designs, yoke and bondage, the Jews should be delivered; and he and his posterity be cut off, because of his vileness, Nah 1:12; and the chapter is concluded with tidings of joy to Judah, who are exhorted to keep their feasts and perform their vows on this occasion, Nah 1:15.
