It's common for people to write the way they speak. If you proofread you may find times you do it yourself.
Heck, a Biblical instructor told us the hideous repetition in, for example, the Book of Ezekiel is likely do to the scribes doing just that.
If you've never read it, do so. It's actually worth the laugh. No disrespect intended. It's just UNBELIEVABLY REPETITIVE TO THE POINT OF BEING SENSELESS.
