Ezekiel 46:12

And if the prince should prepare [as] a thanksgiving a whole burnt-peace-offering to the Lord, and should open for himself the gate looking eastward, and offer his whole burnt offering, and his peace-offerings, as he does on the sabbath-day; then shall he go out, and shall shut the doors after he has gone out.

Now when the prince shall prepare a voluntary burnt offering or peace offerings voluntarily unto 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: then he shall go forth; and after his going forth one shall shut the gate.

When the prince prepares a free will offering, a burnt offering or peace offerings as a free will 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 out; and after his going out one shall shut the gate.
