EZK 46:2

2 The king must enter the courtyard through the entry room of the entryway, and stand alongside the entry post. [Then] the priests must sacrifice the animal that the king brought to be completely burned[on the altar], and also his offering to maintain fellowship with me. The king must worship me at the entrance of the entryway, and then he must go out. [After he leaves], the entryway will not be shut until that evening.
