Albert Barnes Commentary Jeremiah 2:11

"Hath a nation changed [its] gods, which yet are no gods? but my people have changed their glory for that which doth not profit." — Jeremiah 2:11 (ASV)

A nation - A Gentile nation, in strong antithesis to "people," the appellation of Israel.

Their glory - Though the worship of the one true God is a nation’s greatest glory, yet it is irksome because it puts a constraint on human passions.

That which does not profit - Israel had exchanged the prosperity, which was God’s reward for obedience, for the calamities which resulted from idol worship.
