This blessing was given by Joseph Smith Sr. It was given on December 9, 1934 in Kirtland, Ohio. Oliver Cowdery as scribe:
Joseph, my son, I lay my hands upon thy head in the name of the Lord Jesus Christ, to confirm upon thee a father’s blessing. The Lord thy God has called thee by name out of the heavens: thou hast heard his voice from on high from time to time, even in thy youth. The hand of the angel of his presence has been extended toward thee by which thou hast been lifted up and sustained; yea, the Lord has delivered thee from the hands of thine enemies and thou hast been made to rejoice in his salvation: thou has sought to know his ways, and from thy childhood thou hast meditated much upon the great things of his law. Thou hast suffered much in thy youth, and the poverty and afflictions of thy father’s family have been a grief to thy soul. Thou hast desired to see them delivered from bondage, for thou has loved them with a perfect love. Thou hast stood by thy father, and like Shem, would have covered his nakedness, rather than see him exposed to shame: when the daughters of the Gentiles laughed, thy heart has been moved with a just anger to avenge thy kindred. Thou hast been an obedient son: the commands of thy father and the reproofs of thy mother, thou hast respected and obeyed – for all these things the Lord my God will bless thee. Thou hast been called, even in thy youth to the great work of the Lord: to do a work in this generation which no man would do as thyself, in all things according to the will of the Lord. A marvelous work and a wonder has the Lord wrought by thy hand, even that which shall prepare the way for the remnants of his people to come in among the Gentiles, with their fullness, as the tribes of Israel are restored.
I bless thee with the blessings of thy fathers Abraham, Isaac, and Jacob, and even the blessings of thy father Joseph, the son of Jacob. Behold, he looked after his posterity in the last days, when they should be scattered and driven by the Gentiles, and wept before the Lord: he sought siligently to know from whence the son should come who should bring forth the word of the Lord, by which they might be enlightened, and brought back to the true fold, and his eyes beheld thee, my son; his heart rejoiced and his soul was satisfied, and he said, As my blessings are to extend to the utmost bounds of the everlasting hills, as my father’s blessing prevailed above the blessings of his progenitor, and as my branches are to run over the wall, and my seed are to inherit the choice land whereon the Zion of God shall stand in the last days, from among my seed, scattered with the Gentiles, shall a choice Seer arise whose bowles shall be as a fountain of truth, whose loins shall be girded with the girdle of righteousness, whose hands shall be lifted with acceptance before the God of Jacob to turn away his anger from his annointed, whose heart shall meditate great wisdom, whose intelligence shall circumscribe and comprehend the deep things of God, and whose mouth shall uter the law of the just; His feet shall stand upon the neck of his enemies, and he shall walk upon the ashes of those who seek his destruction: with wine and oil shall he be sustained, and he shall feed upon the heritage of Jacob his father: the just shall desire his society, and the upright in heart shall be his companions: No weapon formed against him shall prosper, and though the wicked mar him for a little season, he shall be like one rising up in the heat of wine – he shall roar in his strength, and the Lord shall put to flight his persecutors: he shall be blessed like the fruitful olive, and his memory shall be as sweet as the choice cluster of the first ripe grapes. Like a shief fully ripe, gathered into the garner, so shall he stand before the Lord, having produced a hundred fold. Thus spake my father Joseph. Therefore, my son, I know for a surety that those things will be fulfilled, and I confirm upon thee all these blessings.
Thou shalt like to do the work which the Lord shall command thee: Thou shalt hold the Keys of this ministry, even the presidency of this church, both in time and in eternity. Thy heart shall be enlarged, and thou shalt be able to fill up the measure of thy days according to the will of the Lord. Thou shalt speak the word of the Lord and the earth shall tremble; the mountains shall move and the rivers shall turn out of their course. Thou shalt escape the edge of the sword, and put to flight the armies of the wicked. At thy word the lame shall walk, the deaf shall hear and the blind shall see. Thou shalt be gathered to Zion and in the goodly land thou shalt enjoy thine inheritance; thy children and thy children’s children to the latest generation; for thy name and the names of thy posterity shall be recorded in the book of the Lord, even in the book of blessings and genealogies, for their joy and benefit forever. And now, my son, what more shall I say? Thou art as a fruitful olive and a choice vine: thou shalt be laden with precious fruit. Thousands and tens of thousands shall come to a knowledge of the truth through thy ministry, and thou shalt rejoice with them in the Celestial Kingdom:
Thou shalt stand upon the earth when it shall reel to and fro as a drunken man, and be removed out of its place: thou shalt stand when the mighty judgments go forth to the destruction of the wicked: thou shalt stand on Mount Zion when the tribes of Jacob come shouting from the north, and with thy brethren, the sons of Ephraim, crown them in the name of Jesus Christ: Thou shalt see thy Redeemer come in the clouds of heaven, and with the just receive the hallowed throng with shouts of hallalujahs, praise the Lord. Amen
