Genesis 28:10-12

Now Jacob left Beersheba [never to see his mother again] and traveled toward Haran. And he came to a certain place and stayed overnight there because the sun had set. Taking one of the stones of the place, he put it under his head and lay down there [to sleep]. He dreamed that there was a ladder (stairway) placed on the earth, and the top of it reached [out of sight] toward heaven; and [he saw] the angels of God ascending and descending on it [going to and from heaven]. [John 1:51]
