Mosiah 7:3

And it came to pass that on the morrow, they started to go up, having with them one Ammon, he being a strong and mighty man, and a descendant of Zarahemla; and he was also their leader.

The next day, they started their trip. They took with them a man named Ammon. He was strong and came from Zarahemla. He was also their leader.

The next day they set out, led by a man named Ammon—a strong, capable man descended from Zarahemla.
