I. (1.1) The treatise before this one has contained our opinions on those visions sent from heaven which are classed under the first species; in reference to which subject we delivered our opinion that the Deity sent the appearances which are beheld by man in dreams in accordance with the suggestions of his own nature. But in this treatise we will, to the best of our power, describe those dreams which come under the second species. (1.2) Now the second species is that in which our mind, being moved simultaneously with the mind of the universe, has appeared to be hurried away by itself and to be under the influence of divine impulses, so as to be rendered capable of comprehending beforehand, and knowing by anticipation some of the events of the future. Now the first dream which is akin to the species which I have been describing, is that which appeared on the ladder which reached up to heaven, and which was of this kind. (1.3) "And Jacob dreamed, and behold a ladder was firmly planted on the earth, the head of which reached up to heaven; and the angels of God were ascending and descending on it. And behold there was a ladder firmly planted on the earth, and the Lord was standing steadily upon it; and he said, I am the God of Abraham thy father, and the God of Isaac: be not afraid. The earth on which thou art sleeping I will give unto thee and unto thy seed, and thy seed shall be as the dust of the earth, and it shall be multiplied as the sand on the seashore, and shall spread to the south, and to the north, and to the east; and in thee shall all the kindreds of the earth be blessed, and in thy seed also. And, behold, I am with thee, keeping thee in all thy ways, by whichever thou goest, and I will bring thee again into this land; because I will not leave thee until I have done everything which I have said unto Thee."[genesis 28:12.] (1.4) But the previous considerations of the circumstances of this vision require that we should examine them with accuracy, and then perhaps we shall be able to comprehend what is indicated by the vision. What, then, are the previous circumstances? The scripture tells us, "And Jacob went up from the well of the oath, and came to Charran, and went into a place and lay down there until the sun arose. And he took one of the stones of the place and placed it at his head, and went to sleep in that place." And immediately afterwards came the dream. (1.5) Therefore it is well at the outset to raise a question on these three points:--One, What was the well of the oath, [Ge 26:33.] and why was it called by this name? Secondly, What is Charran, and why, after Jacob had departed from the well beforementioned, did he immediately go to Charran? Thirdly, What was the place, and why, when he was in it, did the sun at once set, and did he go to sleep?
