What does Jeremiah 8:19 mean?

Listen! The cry of my people comes from far away in the land: 'Isn’t the Lord in Zion? Isn’t her king there?' 'Why have they made me angry with their idols and foreign gods?' Jeremiah 8:19 - Modern Text Bible

(The people are desperate, wondering why God isn’t helping, but God responds that their own idolatry is the reason.)
