Alma 27

Now it came to pass in the thirtieth year of the reign of the judges over the people of Nephi, after Moroni had received and had read Helaman’s epistle, he was exceedingly rejoiced because of the welfare, yea, the exceeding success which Helaman had had in obtaining those lands which were lost. Yea, and he did make it known unto all his people in all the land round about in that part where he was, that they might rejoice also.
