Jeremiah 8:7-9

7Even birds know when it is time for them to move to a different place. That is true for storks, doves, swallows and cranes. Birds know when it is time to return, but my people do not know my laws.

8You say, “We are wise because we have the law of the Lord.” But I tell you, your teachers have changed my laws. They teach you lies instead.

9Those wise teachers will be ashamed and upset. Enemies will catch them as their prisoners. They have refused to accept the Lord's message. So they are not really wise.
