Ezekiel 46:2-3

2The prince will enter by way of the porch of the gate from outside, and stand by the post of the gate. Then the kohanim will prepare his burnt offering and his fellowship offerings. He will worship at the threshold of the gate, and then go out. The gate will not be shut until the evening.

3The people of the land will worship at the door of that gate before Adonai on Shabbatot and New Moons.
