Jeremiah 7:15

And I will cast you out of my sight, as I have cast out all your brethren, even the whole seed of Ephraim.

The coming judgment upon Judah and the temple is measured against God's earlier casting of Israel out of His sight. As the whole seed of Ephraim was cast out, so those in Judah who persist in disobedience face the same casting away. This warning will be fulfilled against all who refuse to hear and who reject the light sent to them. It stands therefore as a warning to everyone who has received light but refuses it.
