Here's a breakdown:
* ha-roh-sheth: The "h" is silent, and the "sh" sounds like the "sh" in "ship". The "e" at the end is short, like the "e" in "pet".
* ha-goy-im: The "h" is silent, and the "y" sounds like the "y" in "yes". The "i" at the end is short, like the "i" in "bit".
The two parts are pronounced separately, with a slight pause between them.
