2 Kings 1:41-43

41 And they did still continue to build up churches unto themselves, and adorn them with all manner of precious things. And thus did two hundred and fifty years pass away, and also two hundred and sixty years.

42 And it came to pass that the wicked part of the people began again to build up the secret oaths and combinations of Gadianton.

43 And also the people who were called the people of Nephi began to be proud in their hearts, because of their exceeding riches, and become vain like unto their brethren, the Lamanites.
