JER 4:3

3 This is what Yahweh says to the people of Jerusalem and [the other cities in] Judah: “[Prepare yourselves to receive my messages] like farmers plow up hard ground [in order that they can plant seed in it]. Just as farmers do not [waste good seed by] sowing seeds among thorny plants, [I do not want to waste my time telling you messages that you are not ready to receive].
