Ezekiel 44:3

“Then the prince shall enter by way of the porch of the gate from outside and stand by the post of the gate. Then the priests shall provide his burnt offering and his peace offerings, and he shall worship at the threshold of the gate and then go out; but the gate shall not be shut until the evening.

“And when the prince enters, he shall go in by way of the porch of the gate and go out by the same way.

“And when the prince provides a freewill offering, a burnt offering, or peace offerings as a freewill offering to Yahweh, the gate facing east shall be opened for him. And he shall provide his burnt offering and his peace offerings as he does on the sabbath day. Then he shall go out, and the gate shall be shut after he goes out.
