Alma 15:1

And it came to pass that Alma and Amulek were commanded to depart out of that city; and they departed, and came out even into the land of Sidom; and behold, there they found all the people which had departed out of the land of Ammonihah, who had been cast out and stoned, because they believed in the words of Alma.

Alma and Amulek were told to leave that city. They left and came to the land of Sidom. There they found all the people who had left the land of Ammonihah. These people had been kicked out and stoned because they believed what Alma said.

Alma and Amulek were ordered to leave the city. They traveled to the land of Sidom, where they found all the believers who had fled from Ammonihah—people who had been driven out and stoned because they believed what Alma taught.
