'Beyond' in the Bible

Then I said to the king, “If it pleases the king, let letters be given to me for the governors of the provinces beyond the [Euphrates] River, so that they will allow me to pass through until I reach Judah,

Then I came to the governors of the provinces beyond the [Euphrates] River and gave them the king’s letters. Now the king had sent officers of the army and horsemen with me.
