Jeremiah 21:5

And I myself will fight against you with an outstretched hand and with a strong arm, even in anger, and in fury, and in great wrath.

God himself turns to fight against Judah with outstretched hand and strong arm, in anger and fury and great wrath, as judgment for its rebellion. The declaration stands among clear denunciations of sin that pronounce God's judgment upon his own people. It was uttered amid sorrow over their transgression and earnest appeals for them to return to God, appeals that met with little response.
