Jeremiah

Thus saith the Lord of hosts; If thou wilt walk in my ways, and if thou wilt keep my charge, then thou shalt also judge my house, and shalt also keep my courts, and I will give thee places to walk among these that stand by.

And that ye may put difference between holy and unholy, and between unclean and clean;

For I will give you a mouth and wisdom, which all your adversaries shall not be able to gainsay nor resist.

And they shall teach my people the difference between the holy and profane, and cause them to discern between the unclean and the clean.

Her priests have violated my law, and have profaned mine holy things: they have put no difference between the holy and profane, neither have they shewed difference between the unclean and the clean, and have hid their eyes from my sabbaths, and I am profaned among them.
