Arcana Coelestia #624
624. It is clear that a state which is not a state of the Church is the subject here from the fact that in this verse and those that follow in chapter the name God is used, whereas in previous verses it was Jehovah. When the Church does not exist the name God is used, but when it does exist, it is Jehovah; for example in Genesis 1, when the Church did not exist, He was called God, but in the next chapter when it did, He was called Jehovah God. 'Jehovah' is the holiest of names, and belongs to the Church alone. Not so 'God', for no nation was without gods. Consequently the same holiness was not attached to the name God. Nobody was allowed to utter the name Jehovah except him who had knowledge of the true faith; but anyone was allowed to utter the name God.
Isaiah 28:7-9
7
They also reel with wine, and stagger with strong drink. The priest and the prophet reel with strong drink. They are swallowed up by wine. They stagger with strong drink. They err in vision. They stumble in judgment.

For all tables are completely full of filthy vomit and filthiness.

Whom will he teach knowledge? To whom will he explain the message? Those who are weaned from the milk, and drawn from the breasts?
