Zemnarihah was a Captain of Gadianton robbers around A.D. 21 who laid siege to the Nephites hoping they would surrender. Because the Nephites had plenty of provisions it was impossible for the robbers to have any effect upon the Nephites. The robbers only had wild game for food which became scarce, causing them hunger. The Nephites marched out continuously and killed tens of thousands. Zemnarihah withdrew and marched his men northward.
Gidgiddoni, leading the Nephites by night, got beyond the robbers and in the morning met them in their front and rear. Thousands of the robbers were taken prisoner and the rest slain. Zemnarihah was hanged from a tree. The tree was felled and the Nephites loudly cried:
May the Lord preserve his people in righteousness and in holiness of heart, that they may cause to be felled to the earth all who shall seek to slay them because of power and secret combinations, even as this man hath been felled to the earth.
May the God of Abraham, and the God of Isaac, and the God of Jacob, protect this people in righteousness, so long as they shall call on the name of their God for protection.
They began singing and praising God, were joyful and shed tears because of the great goodness of God, for they knew it was because of their repentance and their humility that they had been saved from their enemies.
