Yehezkiel 46:2

46:2 The prince will enter by way of the porch of the gate from the outside, and will stand by the doorpost of the gate. The priests will provide his burnt offering and his peace offerings, and he will bow down at the threshold of the gate and then go out. But the gate will not be closed until evening.

Yehezkiel 46:12

46:12 When the prince provides a freewill offering, a burnt offering, or peace offerings as a voluntary offering to the Lord, the gate facing east will be opened for him, and he will provide his burnt offering and his peace offerings just as he did on the Sabbath. Then he will go out, and the gate will be closed after he goes out. ¹
