'Side' in the Bible

We are informing the king that if that city is rebuilt and its walls finished, it will mean that you will have no possession in the province west of the [Euphrates] River.”

At that time Tattenai, the governor of the province on the west side of the [Euphrates] River, and Shethar-bozenai and their colleagues came to them and said, “Who issued you a decree and authorized you to rebuild this temple and to restore this wall (shrine)?”

This is a copy of the letter that Tattenai, governor of the province west of the [Euphrates] River, and Shethar-bozenai and his associates, the officials who were west of the River, sent to Darius the king.

Then Tattenai, governor of the province west of the [Euphrates] River, with Shethar-bozenai and their associates carried out the decree with due diligence, just as King Darius had sent and commanded.
