What does Jeremiah 2:5-13 mean?

Thus says the LORD: “What wrong did your fathers find in me that they went far from me, and went after worthlessness, and became worthless? They did not say, ‘Where is the LORD who brought us up from the land of Egypt, who led us in the wilderness, in a land of deserts and pits, in a land of drought and deep darkness, in a land that none passes through, where no man dwells?’ And I brought you into a plentiful land to enjoy its fruits and its good things. But when you came in, you defiled my land and made my heritage an abomination. The priests did not say, ‘Where is the LORD?’ Those who handle the law did not know me; the shepherds transgressed against me; the prophets prophesied by Baal and went after things that do not profit. “Therefore I still contend with you, declares the LORD, and with your children’s children I will contend. For cross to the coasts of Cyprus and see, or send to Kedar and examine with care; see if there has been such a thing. Has a nation changed its gods, even though they are no gods? But my people have changed their glory for that which does not profit. Be appalled, O heavens, at this; be shocked, be utterly desolate, declares the LORD, for my people have committed two evils: they have forsaken me, the fountain of living waters, and hewed out cisterns for themselves, broken cisterns that can hold no water.
