Genesis 28

"And he took one of the stones of that place and put it at his head, and he lay down in that place to sleep. Then he dreamed, and behold, a ladder was set up on the earth, and its top reached to heaven; and there the angels of God were ascending and descending on it.  And behold, the Lord stood above it and said: “I am the Lord God of Abraham your father and the God of Isaac; the land on which you lie I will give to you and your descendants." vv. 11-13

Read chapter 28.

Why do people refer to this as Jacob's ladder when it clearly is God's ladder?  Jacob is using a stone as a pillow when he has this dream.  I'm sure many of us would gladly trade our pillow with him if it meant getting a vision like this.  "God's time to visit His people with His comforts, is when they are most destitute of other comforts and other comforters" (Matthew Henry's Concise Commentary).  When we are most afraid or cast out or alone do we look for the God of comfort and allow Him to be that for us?  This ladder with Jehovah at the top is a symbol of Him being the one and only way to heaven.  He is and always has been the way, the truth, and the life (John 14:6).  Even angels have this one way.  Interestingly they're ascending and descending between heaven and earth.  Angels among men truly and may not even know it!
