'Retinue' in the Bible

“Before I was aware [of what was happening], my desire had brought meInto the area of the princes of my people [the king’s retinue].”

Now therefore, listen carefully, the Lord is about to bring on them the waters of the [Euphrates] River, strong and abundant—The king of Assyria and all his glory;And it will rise over all its channels and canals and go far beyond its banks.
