"Jacob=Israel"

And Jacob went out from Beer-sheba, and went toward Haran. 

And he lighted upon a certain place, and tarried there all night, because the sun was set; and he took of the stones of that place, and put them for his pillows, and lay down in that place to sleep. And he dreamed, and behold a ladder set up on the earth, and the top of it reached to heaven: and behold the angels of God ascending and descending on it. And, behold, the KING YHVH (YEHOVAH) stood above it, and said, I am the KING Almighty of Abraham your father, and the ALMIGHTY of Isaac: the land where on you lie, to thee will I give it, and to your seed (descendants); and your seed shall be as the dust of the earth, and you shalt spread abroad to the west, and to the east, and to the north, and to the south: and in thee and in your seed (descendants) shall all the families of the earth be blessed. And, behold, I am with thee, and will keep thee in all places whither you're going, and will bring thee again into this land; for I will not leave thee, until I have done that which I have spoken to thee of. 

And Jacob woke out of his sleep, and he said, Surely the Almighty YHVH (YEHOVAH) is in this place; and I knew it not. And he was afraid, and said, how dreadful is this place! this is none other but the house of Almighty YHVH (YEHOVAH), and this is the gate of heaven. 

And Jacob rose up early in the morning, and took the stone that he had put for his pillows, and set it up for a pillar, and poured oil upon the top of it. And he called the name of that place Beth-el: but the name of that city was called Luz at the first. 

And Jacob vowed a vow, saying, If Almighty YHVH (YEHOVAH) will be with me, and will keep me in this way that I go, and will give me bread to eat, and raiment to put on, so that I come again to my father’s house in peace; then shall the Lord be my God: and this stone, which I have set for a pillar, shall be God’s house: and of all that thou shalt give me I will surely give the tenth unto thee.
