119 And the Lord said
Send and go with your son and enter the cavity of the rock
and see to it that your son obtains the top two stones which are joined And cause him to take them unto his bosom For with these stones he can see And the stones are each one called Ur which is to say the light of my Father And together they will allow your son to see as if through the eyes of Anokeesed And together they are called Urim
120 But remember no one but your son Enoch can touch them
And if any man touches them when looking therein they will not work for that man And no man may look there with except he be called upon to do so by Anokeesed in heaven lest he perish
121 And if all my words are followed without turning this way or that way and if all my instructions to you for your son are followed then the light of my Father like unto that of the menorah bush flowers will shine and enlighten his eyes And all things can become known to him And the light of God will shine forth in the stones like three tongues of fire And he shall thus be called seer
Baraka (Enoch's Mother) the worshiper said As I live you are my rock of witness And you are witness to my word that these stones will enlighten the eyes of men to see through the eyes of Anokeesed And now before Him and His word it is established forever upon the earth and the rock said It is so
19 And in his preparations Enoch had been instructed that when using the Urim he was to see that he must not touch the Urim for nothing could touch it that had sin but it had to be held by something that only felt perfection for it to work as the Lord intended
21 And the Lord told him it would be best if he would fasten it upon the staff with a twisted reed called the arah reed which is known as papyrus and it is given life by the presence of Messiah that feels discovering the truth and to make it bare before you and these things are very powerful elements of righteousness before the God of heaven

Here is a letter describing the Urim Joseph Smith
A "gold book," consisting of a number of plates of gold, fastened together in the shape of a book by wires of the same metal, had been dug up in the northern part of the state of New York, and along with the book an enormous pair of "gold spectacles"! These spectacles were so large, that, if a person attempted to look through them, his two eyes would have to be turned towards one of the glasses merely, the spectacles in question being altogether too large for the breadth of the human face. Whoever examined the plates through the spectacles, was enabled not only to read them, but fully to understand their meaning. All this knowledge, however, was confined at that time to a young man, who had the trunk containing the book and spectacles in his sole possession. This young man was placed behind a curtain, in the garret of a farm house, and, being thus concealed from view, put on the spectacles occasionally, or rather, looked through one of the glasses, decyphered the characters in the book, and, having committed some of them to paper, handed copies from behind the curtain, to those who stood on the outside. Not a word, however, was said about the plates having been decyphered "by the gift of God." Every thing, in this way, was effected by the large pair of spectacles.He informed me that they were in a trunk with the large pair of spectacles. I advised him to go to a magistrate and have the trunk examined. He said the "curse of God" would come upon him should he do this.
