Ezekiel 44:4-9 - Rules For Admission To The Temple
4 And he will bring me the way of the gate of the north to the face of the house: and I shall see, and behold, the glory of Jehovah filled the house of Jehovah: and I shall fall upon my face. 5 And Jehovah will say to me, Son of man, set thy heart, and see with thine eyes, and hear with thine ears all which I speak to thee concerning all the laws of the house of Jehovah, and concerning all its instructions; and set thy heart to the entering of the house, and all the goings out of the holy place.
6 And thou shalt say to the perverse to the house of Israel, Thus said the Lord Jehovah: Enough for you of all your abominations, O house of Israel. 7 In your bringing in the sons of the stranger, uncircumcised of heart and uncircumcised of flesh, to be in my holy place to profane it, my house, in your bringing near my bread, the fat and the blood, and they will break my covenant by all your abominations. 8 And ye watched not the watches of my holy place: and ye set for watching of my watches in my holy place for yourselves.
9 Thus said the Lord Jehovah: Every son of the stranger, uncircumcised of heart and uncircumcised of flesh, shall not come in to my holy place, to every son of the stranger which is the midst of the sons of Israel.
