What does Jeremiah 35:13 mean?

God told Jeremiah, Go and tell the people of Judah and Jerusalem: 'Won't you ever learn to listen to me and do what I say? Look at the Rechabites! They obey their ancestor's command, but you ignore me completely.' Jeremiah 35:13 - Modern Text Bible

(God uses the Rechabites as an example to shame the people of Judah for their disobedience.)
