C. F. Keil and Franz Delitzsch on Jeremiah 23:12

Jer 23:12

For this the Lord will punish them. Their way shall be to them as slippery places in darkness. This threatening is after the manner of Psa 35:6, where חשׁך are joined, changed by Jeremiah to the words in the text. The passage cited shows that we may not separate בּאפלה from חלקלקּות, as Ew. does, to join it to the following ידּחוּ. Their way shall resemble slippery places in the dark, when one may readily slip and fall. Besides, they are to be thrust, pushed, so that they must fall on the slippery path (ידּחוּ from דּחח = דּחה, Psa 35:5; "therein" to be referred to "their way"). The clause: "for I bring evil," etc., is formed after Jer 11:23.
