Ezekiel 46:12

12

And when the prince shall prepare a freewill-offering, a burnt-offering or peace-offerings as a freewill-offering unto Jehovah, one shall open for him the gate that looketh toward the east; and he shall prepare his burnt-offering and his peace-offerings, as he doth on the sabbath day: then he shall go forth; and after his going forth one shall shut the gate.
