Ezekiel 46:12 When the prince shall prepare a freewill-offering, a burnt offering or peace-offerings as a freewill-offering to Yahweh, one shall open for him the gate that looks toward the east; and he shall prepare his burnt offering and his peace-offerings, as he does on the Sabbath day: then he shall go forth; and after his going forth one shall shut the gate.
