What does Jeremiah 14:1-12 mean?

The word of the LORD that came to Jeremiah concerning the drought: “Judah mourns, and her gates languish; her people lament on the ground, and the cry of Jerusalem goes up. Her nobles send their servants for water; they come to the cisterns; they find no water; they return with their vessels empty; they are ashamed and confounded and cover their heads. Because of the ground that is dismayed, since there is no rain on the land, the farmers are ashamed; they cover their heads. Even the doe in the field forsakes her newborn fawn because there is no grass. The wild donkeys stand on the bare heights; they pant for air like jackals; their eyes fail because there is no vegetation. “Though our iniquities testify against us, act, O LORD, for your name’s sake; for our backslidings are many; we have sinned against you. O you hope of Israel, its savior in time of trouble, why should you be like a stranger in the land, like a traveler who turns aside to tarry for a night? Why should you be like a man confused, like a mighty warrior who cannot save? Yet you, O LORD, are in the midst of us, and we are called by your name; do not leave us.” Thus says the LORD concerning this people: “They have loved to wander thus; they have not restrained their feet; therefore the LORD does not accept them; now he will remember their iniquity and punish their sins.” The LORD said to me: “Do not pray for the welfare of this people. Though they fast, I will not hear their cry, and though they offer burnt offering and grain offering, I will not accept them. But I will consume them by the sword, by famine, and by pestilence.”
