Yeremia 8:9

8:9 Your wise men will be put to shame.

They will be dumbfounded and be brought to judgment. ¹ 

Since they have rejected the word of the Lord,

what wisdom do they really have?

Yeremia 9:5

9:5 One friend deceives another

and no one tells the truth.

These people have trained themselves ²  to tell lies.

They do wrong and are unable to repent.

[8:9]  ¹ tn Heb “be trapped.” However, the word “trapped” generally carries with it the connotation of divine judgment. See BDB 540 s.v. לָכַד Niph.2, and compare usage in Jer 6:11 for support. The verbs in the first two lines are again the form of the Hebrew verb that emphasizes that the action is as good as done (Hebrew prophetic perfects).

[9:5]  ² tn Heb “their tongues.” However, this is probably not a natural idiom in contemporary English and the tongue may stand as a part for the whole anyway.
