What does Jeremiah 20:13 mean?

For I have heard the defaming of many, “Terror on every side! Denounce, and we will denounce him!” say all my familiar friends, those who watch for my fall. “Perhaps he will be persuaded, and we will prevail against him, and we will take our revenge on him.”

But Yahweh is with me as an awesome mighty one. Therefore my persecutors will stumble, and they won’t prevail. They will be utterly disappointed, because they have not dealt wisely, even with an everlasting dishonor which will never be forgotten.

But, Yahweh of Armies, who tests the righteous, who sees the heart and the mind, let me see your vengeance on them; for to you I have revealed my cause.

Cursed is the day in which I was born. Don’t let the day in which my mother bore me be blessed.

Cursed is the man who brought news to my father, saying, “A boy is born to you,” making him very glad.

Let that man be as the cities which Yahweh overthrew, and didn’t repent. Let him hear a cry in the morning, and shouting at noontime;
