Ezekiel 46:11-12

Leeser(i) 11 And on the feasts and on the appointed festivals shall the meat-offering be an ephah for each bullock, and an ephah for each ram, and for the sheep as his hand may be able to give, and a hin of oil for every ephah. 12 And when the prince doth prepare as a voluntary gift a burnt-offering, or a peace-offering, as a voluntary gift unto the Lord: then shall be opened for him the gate that looketh toward the east, and he shall prepare his burnt-offering and his peace-offering, as he usually doth on the sabbath-day; and he shall go out, and the gate shall be locked after his going out.
