"Spirtually speaking, Israel has worn rags and eaten dust long enough. Now is the time for her to come forth and assume the dignity and power that were once hers. In a revealed commentary on this passage given through the Prophet Joseph Smith, the Lord affirmed that Isaiah had reference to those of the last days who would be called to hold the priesthood, establish Zion, and bring about the redemption of Israel. 'To put on her strength,' Joseph was told, meant that Israel would again be clothed in the 'authority of the priesthood' which she had a 'right to by lineage.' The loosing herself from the bands of her neck would be the breaking of the 'curses of God upon her' in her scattered and apostate condition as she returned to the Lord from whence she had fallen. (D&C 113:7-10.)
"It was a paraphrase of these verses that Moroni chose as a conclusion to the Book of Mormon. Speaking to scattered Israel of the last days, Moroni said, 'Awake, and arise from the dust, O Jerusalem; yea, and put on thy beautiful garments, O daughter of Zion; and strengthen thy stakes and enlarge thy borders for ever, that thou mayest no more be confounded, that the covenants of the Eternal Father which he hath made unto thee, o house of Israel, may be fulfilled' (Moroni 10:31)." (Joseph Fielding McConkie, Gospel Symbolism, pp. 141-2)

"Put on thy beautiful garments, O daughters of Zion. Live up to the great and magnificent inheritance which the Lord God, your Father in Heaven, has provided for you. Rise above the dust of the world. Know that you are daughters of God, children with a divine birthright. Walk in the sun with your heads high, knowing that you are loved and honored, that you are a part of his kingdom, and that there is for you a great work to be done which cannot be left to others." (Ensign, November 1983, pp. 83-84.)
