'Beyond the River' in the Bible

And saying to the king, If good to the king letters shall be given to me to the prefects beyond the river, that they shall cause me to pass over till I shall come to Judah.

And I shall come to the prefects beyond the river, and I shall give to them the letter of the king. And the king will send with me chiefs of strength and horsemen.

And upon their band held fast Melatiah the Gibeonite, and Jadon the Meronothite, the men of Gibeon, and Mizpeh to the throne of the prefect beyond the river.
