What does Jeremiah 35:13 mean?

but we have lived in tents, and have obeyed, and done according to all that Jonadab our father commanded us.

But when Nebuchadnezzar king of Babylon came up into the land, we said, ‘Come, and let us go to Jerusalem for fear of the army of the Chaldeans, and for fear of the army of the Syrians; so we will dwell at Jerusalem.’”

Then Yahweh’s word came to Jeremiah, saying,

“The words of Jonadab the son of Rechab that he commanded his sons, not to drink wine, are performed; and to this day they drink none, for they obey their father’s commandment; but I have spoken to you, rising up early and speaking, and you have not listened to me.

I have sent also to you all my servants the prophets, rising up early and sending them, saying, ‘Every one of you must return now from his evil way, amend your doings, and don’t go after other gods to serve them, then you will dwell in the land which I have given to you and to your fathers:’ but you have not inclined your ear, nor listened to me.

The sons of Jonadab the son of Rechab have performed the commandment of their father which he commanded them, but this people has not listened to me.”’
