What does Jeremiah 23:13 mean?

For the land is full of adulterers; for because of the curse the land mourns. The pastures of the wilderness have dried up. Their course is evil, and their might is not right;

for both prophet and priest are profane. Yes, in my house I have found their wickedness,” says Yahweh.

Therefore their way will be to them as slippery places in the darkness. They will be driven on, and fall therein; for I will bring evil on them, even the year of their visitation,” says Yahweh.

In the prophets of Jerusalem I have also seen a horrible thing: they commit adultery and walk in lies. They strengthen the hands of evildoers, so that no one returns from his wickedness. They have all become to me as Sodom, and its inhabitants as Gomorrah.”

Therefore Yahweh of Armies says concerning the prophets: “Behold, I will feed them with wormwood, and make them drink the water of gall; for from the prophets of Jerusalem ungodliness has gone out into all the land.”

Yahweh of Armies says, “Don’t listen to the words of the prophets who prophesy to you. They teach you vanity. They speak a vision of their own heart, and not out of the mouth of Yahweh.
