Ezekiel 46:12

Now, when the prince shall prepare a voluntary burnt offering or peace-offerings voluntarily unto the Lord, by reason of special inward impulse, a joyful readiness to serve the Lord, one shall then open him the gate that looketh toward the east, and he shall prepare his burnt offering and his peace-offerings, as he did on the Sabbath-day, this rule therefore applying to all festivals; then he shall go forth, and after his going forth one shall shut the gate, so that the rule concerning its being closed would always be observed. The passage rightly sets forth the fine rivalry which may exist between the various ranks and classes of people in their acts of homage and adoration to God.
