Im not picking and choosing.
The bible is a collection of 66 different books. Just like a library you are not supposed to read all books in the same style, History books in one way, fictional in another and so on. You can tell from the style how books are supposed to be read.
When is Psalms it says: the lord is my shepherd, I shall no be in want (psalm 23)
It is has a very different style to Historical passages in the New Testament. The same is true for Genesis, poetry and historical journal
