11At the festivals and appointed feasts, the grain offering shall be an ephah with a bull, an ephah with a ram, and as much as one is able to give with the lambs, along with a hin of oil per ephah.
12When the prince makes a freewill offering to the LORD, whether a burnt offering or a peace offering, the gate facing east must be opened for him. He is to offer his burnt offering or peace offering just as he does on the Sabbath day. Then he shall go out, and the gate must be closed after he goes out.
— Ezekiel 46:11-12
