Ezekiel 44:9

Now God renews his former law against the permitting of the wicked and heathens to enter his sanctuary. None, of what quality soever, what interest soever they make, though princes, nobles, learned, travellers, that come to view nations and the rarities of them; none of these, or such like, shall on any colour of pretence be brought into my sanctuary. Perhaps Solomon showed Sheba's queen too much, we are sure Hezekiah showed the ambassadors too much, yet we read not that either of them showed the sanctuary.
