Ezekiel 44:4-5

Also He brought me by way of the north gate to the front of the temple; so I looked, and behold, the glory of the Lord filled the house of the Lord; and I fell on my face. And the Lord said to me, “Son of man, mark well, see with your eyes and hear with your ears, all that I say to you concerning all the ordinances of the house of the Lord and all its laws. Mark well who may enter the house and all who go out from the sanctuary. — NKJV
