John Wesley on Jeremiah 6:6

Said - To the Chaldeans: God would have the Jews to know, that they have not so much to do with the Chaldeans as with him; that they are his rod to scourge them for their sins. And thus God is said to hiss for such whom he will employ in such work, Isa 5:26 7:18. And he styles himself the Lord of hosts, to shew that it is in vain to contend in battle with them, whom he sends forth. Trees - Such as you may have need of to raise up works against the strong places. Cast a mount - Throw up one continued trench, as a mount round about it. Oppression - There are found in her all kinds of oppression and injustice.
