In this clip they had to destroy the mentioned verses in Proverbs, so that they would not have to admit that God has a son. They basically relegated them to the level of poetry, which is something that anyone can do to Bible verses that they are inconvenienced by. They then tried to say that these verses were talking about Solomon, but you could tell that their reasoning was just based on guesswork.
