John Trapp on Jeremiah 2:5

Ver. 5. What iniquity have your Fathers found in me?] How unreaſonable was their Apoſtacy? and how ſenſeleſs is your pleading of their example? nothing is more irrational then irreligion.

That they are gone far from me] Are ye weary of receiving ſo many benefits by one man? ſaid Themiſtocles to his ungrateful Country-men.

And have walked after vanity] An Idol is nothing at all, but only in the vain opinion of the Idolater.

And are become vain] ſc. In their imaginations, Rom. 1.21. as vain as their very Idols, Pſal. 115.8.
