This chapter begins with several exhortations to repentance; first to Israel, or the ten tribes, to return to the Lord with their whole hearts, and put away their abominations, and serve him in sincerity and uprightness of soul; with promises of rest and safety to themselves; and that it would have a happy influence on the Gentiles, and issue in their conversion; who would hereupon bless themselves in the Lord, and glory in him, Jer 4:1,2, and next to the inhabitants of Judah and Jerusalem, to show a concern for renewing and sanctifying grace, signified by various metaphors, lest they should be consumed with the fire of divine wrath, Jer 4:3,4 and then the destruction of that land and city is foretold and described, partly by what was introductory to it, and the proclamation of it, signified by blowing the trumpet, and setting up the standard, Jer 4:5,6,15,19,20, by an account of the destroyers, their cruelty, swiftness, and diligence, Jer 4:7,13,16,17, and of the destruction itself, compared to a violent wind, Jer 4:11,12, by the effect it should have upon the inhabitants of all sorts, high and low, Jer 4:8,9, and had upon the prophet himself, Jer 4:10,19,21, and by the cause and ground of it, the sins of the people, which they are called upon to repent of, Jer 4:14,17,18,22 and by a vision the prophet had of the dreadful desolation of the land, Jer 4:23-29 and by the vain and false hopes the people would have of their recovery, and the great anxiety and distress they would be in, Jer 4:30,31.
