The Bible

[Edwardo Piet]

Not if it's literal or a metaphor that is - literally - in an accepted dictionary. The meaning is only vague if the meaning is being made up on the spot, e.g: A metaphor being created by the author on the spot - and so not in an accepted dictionary.

What a meaning actually is and what you think is meant by it are separate.

I think we're talking across each other here, because we're using two different senses of the word "meaning".

"What did he mean when he said that?" vs "What does this word mean?"
When I am using the word 'meaning', I am referring to the semantic content, in particular, the content wished to be expressed by a particular person.

Oh good, because that was exactly my point. Just because someone intends to mean a certain thing doesn't mean the actual meaning (in the other sense of the definition "meaning") is actually any different.

Knowing all the definitions of the words and phrases used in a sentence is not enough to know the content wished to be expressed by the sentence. Definitions underdetermine the semantic content.

I disagree. Without definitions things would be much more awkward. Dictionaries help, for example, because they make definitions more specific and agreed upon.

It's not enough to "know" what was meant in the sentence. But what is? We can't know anything besides tautology and our own self-awareness.

The meaning of what is expressed means whatever it means. We either mean X or we don't mean X. Whether others know what we mean or not is another matter.
