'Tattenai' in the Bible

At the same time, Tattenai, ruler of the land across the river, and Shethar-bozenai, and their men, came to them and said, Who gave you orders to go on building this house and this wall?

This is a copy of the letter which Tattenai, the ruler of the land across the river, and Shethar-bozenai and his friends the Apharsachites, living across the river, sent to Darius the king:

So now, Tattenai, ruler of the land across the river, and Shethar-bozenai and your people the Apharsachites across the river, keep far from that place:

Then Tattenai, the ruler across the river, and Shethar-bozenai and their people, because of the order given by King Darius, did as he had said with all care.
