Genesis 28:8-18

8 Esav saw that the daughters of Kana`an didn't please Yitzchak, his father.
9 Esav went to Yishma'el, and took, besides the wives that he had, Machalat the daughter of Yishma'el, Avraham's son, the sister of Nevayot, to be his wife.
10 Ya`akov went out from Be'er-Sheva, and went toward Haran.
11 He came to a certain place, and stayed there all night, because the sun had set. He took one of the stones of the place, and put it under his head, and lay down in that place to sleep.
12 He dreamed. Behold, a stairway set up on the eretz, and the top of it reached to heaven. Behold, the angels of God ascending and descending on it.
13 Behold, the LORD stood above it, and said, "I am the LORD, the God of Avraham your father, and the God of Yitzchak. The land whereon you lie, to you will I give it, and to your seed.
14 Your seed will be as the dust of the eretz, and you will spread abroad to the west, and to the east, and to the north, and to the south. In you and in your seed will all the families of the eretz be blessed.
15 Behold, I am with you, and will keep you, wherever you go, and will bring you again into this land. For I will not leave you, until I have done that which I have spoken of to you."
16 Ya`akov awakened out of his sleep, and he said, "Surely the LORD is in this place, and I didn't know it."
17 He was afraid, and said, "How dreadful is this place! This is none other than God's house, and this is the gate of heaven."
18 Ya`akov rose up early in the morning, and took the stone that he had put under his head, and set it up for a pillar, and poured oil on the top of it.
