Informal words

Did Elijah use informal words like dad, okay, or um. 

He did.

We all do.

Are informal words from Elijah “anachronisms”?

No. Anachronisms belong in a different time than Elijah’s, such as airplane or computer.  People of all times have used dad, okay, or um.

I suspect books and movies which portray hyper spiritual Biblical characters speaking King James English from an echo chamber have warped our understanding.

Most of us find it difficult to think of Elijah as a normal guy just like us. But he “was a man subject to like passions as we are,”[mfn]James 5:17 [/mfn] and he used informal words.
