[Patriarchal Blessings] Patriarchal Blessing of Elizabeth Ann Whitney given by Joseph Smith, Sr. on September 14, 1835
... for thou art bone of his bone and flesh of his flesh, and the Lord has so ordained that those of the same family and descent might be one to fulfil his purposes; for thou art of the same lineage of thy husband, thy life has been hid also, and thou mayest rejoice, for thy posterity shall be blessed. Thou hast a gift to sing the songs of Zion [sing in tongues], and if thou wilt be humble before the Lord & keep all his commandments, it shall be increased. (1)
