Ezekiel 44:6

As for the prince, he shall sit in it as prince to eat bread before the LORD. He shall enter by the way of the porch of the gate, and shall go out the same way.”

Then he brought me by the way of the north gate before the house; and I looked, and behold, the LORD’s glory filled the LORD’s house; so I fell on my face.

The LORD said to me, “Son of man, mark well, and see with your eyes, and hear with your ears all that I tell you concerning all the ordinances of the LORD’s house and all its laws; and mark well the entrance of the house, with every exit of the sanctuary.

in that you have brought in foreigners, uncircumcised in heart and uncircumcised in flesh, to be in my sanctuary, to profane it, even my house, when you offer my bread, the fat and the blood; and they have broken my covenant, to add to all your abominations.

You have not performed the duty of my holy things; but you have set performers of my duty in my sanctuary for yourselves.”

The Lord GOD says, “No foreigner, uncircumcised in heart and uncircumcised in flesh, shall enter into my sanctuary, of any foreigners who are among the children of Israel.
