Ezekiel 46:2; Ezekiel 46:12

2 The prince is to enter from the outside through the portico of the gateway and stand by the gatepost. The priests are to sacrifice his burnt offering and his fellowship offerings. He is to bow down in worship at the threshold of the gateway and then go out, but the gate will not be shut until evening.

12 “ ‘When the prince provides a freewill offering to the LORD—whether a burnt offering or fellowship offerings—the gate facing east is to be opened for him. He shall offer his burnt offering or his fellowship offerings as he does on the Sabbath day. Then he shall go out, and after he has gone out, the gate will be shut.
