Ezekiel 46:2-3

2The prince should enter from the outside by way of the gate’s portico and stand at the gate’s doorpost while the priests sacrifice his burnt offerings and fellowship offerings. He will bow in worship at the gate’s threshold and then depart, but the gate is not to be closed until evening.

3The people of the land will also bow in worship before the Lord at the entrance of that gate on the Sabbaths and New Moons.
