'Miles' in the Bible

Jeroboam’s wife did so. She got up and went [twenty miles] to Shiloh, and came to the house of Ahijah. Now Ahijah could not see, because his eyes were dim from old age.

Then the hand of the Lord came upon Elijah [giving him supernatural strength]. He girded up his loins and outran Ahab to the entrance of Jezreel [nearly twenty miles].

And Elijah was afraid and arose and ran for his life, and he came to Beersheba which belongs to Judah, and he left his servant there.
