The master of the palace had similar functions at the court of Judah. Announcing the promotion of Elyaqim, Isaiah 22:22 says: 'I lay the key of the house of David upon his shoulder, if he opens, none will shut; if he shuts, none will open.' The Egyptian vizier's instructions are described in a very similar fashion. Every morning 'the vizier will send someone to open the gates of the kings house, to admit those who have to enter, and to send out those who have to go out.' One is reminded of the Lord's words to Peter, the Vizier of the Kingdom of Heaven (Matthew 16:19).
