Genesis 28:10

8And Esau seeing that the daughters of Canaan pleased not Isaac his father;

9Then went Esau unto Ishmael, and took unto the wives which he had Mahalath the daughter of Ishmael Abraham’s son, the sister of Nebajoth, to be his wife.

10And Jacob went out from Beersheba, and went toward Haran.

11And 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.

12And 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.
