Mosiah 19:24

And it came to pass that after they had ended the ceremony, that they returned to the land of Nephi, rejoicing, because their wives and their children were not slain; and they told Gideon what they had done to the king.

After that, they went back to the land of Nephi. They were happy because their wives and children were still alive. They told Gideon what they did to the king.

After the funeral rites were finished, they all returned to the land of Nephi, celebrating that their families had survived. They told Gideon what had happened to the king.
