Ezekiel 46:9

CLV(i) 9 And in the coming in of the people of the land before Yahweh at appointed times, he who has come in the way of the north gate to bow himself, goes out the way of the south gate, and he who has come in the way of the south gate, goes out by the way of the north gate:he does not turn back the way of the gate by which he came in, but over-against it he goes out."
