Ezekiel 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.

Ezekiel 46:20

46:20 He said to me, “This is the place where the priests will boil the guilt offering and the sin offering, and where they will bake the grain offering, so that they do not bring them out to the outer court to transmit holiness to the people.”
