2 Kings 11:5-6

11:5 He ordered them, “This is what you must do. One third of the unit that is on duty during the Sabbath will guard the royal palace. 11:6 Another third of you will be stationed at the Foundation Gate. Still another third of you will be stationed at the gate behind the royal guard. You will take turns guarding the palace.

Ezekiel 44:2-3

44:2 The Lord said to me: “This gate will be shut; it will not be opened, and no one will enter by it. For the Lord, the God of Israel, has entered by it; therefore it will remain shut. 44:3 Only the prince may sit in it to eat a sacrificial meal before the Lord; he will enter by way of the porch of the gate and will go out by the same way.”

Ezekiel 46:2-3

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. 46:3 The people of the land will bow down at the entrance of that gate before the Lord on the Sabbaths and on the new moons.
