Jeremiah 8:4-7

4“You are to say to them: This is what the Lord says: Do people fall and not get up again? If they turn away, do they not return?

5Why have these people turned away? Why is Jerusalem always turning away? They take hold of deceit; they refuse to return.

6I have paid careful attention. They do not speak what is right. No one regrets his evil, asking, ‘What have I done?’ Everyone has stayed his course like a horse rushing into battle.

7Even storks in the sky know their seasons. Turtledoves, swallows, and cranes are aware of their migration, but my people do not know the requirements of the Lord.
