Ezekiel 46:2-3

2The prince shall enter by the porch (portico) of the gate from outside and stand by the post of the gate. The priests shall prepare and provide his burnt offering and his peace offerings, and he shall worship at the threshold of the gate and then go out; but the gate shall not be shut until evening.

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