2 Nephi 1:31

Wherefore, because thou hast been faithful, thy seed shall be blessed with his seed, that they dwell in prosperity long upon the face of this land; and nothing, save it shall be iniquity among them, shall harm or disturb their prosperity upon the face of this land forever.—

“So because you have been faithful, your children will be blessed with his children. They will live in happiness for a long time in this land. Nothing will hurt or disturb their happiness in this land forever, except sin among them.”

“Because you’ve been faithful, your descendants will be blessed alongside his. They’ll live and thrive in this land. Nothing will harm their prosperity here—unless they turn to evil.”
