Иеремия 4:9

When this wrath bursts over them, the rulers and leaders of the people will be perplexed and helpless. The heart, i.e., the mind, is lot. For this use of לב, cf. Job 12:3; Job 34:10; Pro 7:7, etc. נשׁמּוּ, be paralyzed by terror, like the Kal in Jer 2:12. The prophets are mentioned last, because Jer 4:10 cites a word of prophecy whereby they seduced the people into a false security.

It should seem that the first two verses of this chapter might better have been joined to the close of the foregoing chapter, for they are directed to Israel, the ten tribes, by way of reply to their compliance with God's call, directing and encouraging them to hold their resolution (Jer 4:1, Jer 4:2). The rest of the chapter concerns Judah and Jerusalem. I. They are called to repent and reform (Jer 4:3, Jer 4:4). II. They are warned of the advance of Nebuchadnezzar and his forces against them, and are told that it is for their sins, from which they are again exhorted to wash themselves (Jer 4:5-18). III. To affect them the more with the greatness of the desolation that was coming, the prophet does himself bitterly lament it, and sympathize with his people in the calamities it brought upon them, and the plunge it brought them to, representing it as a reduction of the world to its first chaos (Jer 4:19-31).

4:9 The impact of the foreign invasion would show Judah’s leaders that they were not as invincible as they believed (48:41; Isa 22:3-5).
