Isaac blesses Jacob, then prohibits him from marrying a foreign woman. This negative attitude toward marriage with foreigners is pretty typical in Genesis (see also 24:3-4; 26:34-35; 27:46). Instead, Jacob's supposed to marry a woman from Rebekah's family.
Isaac says that the deity will help Jacob have lots of babies, and adds that Jacob is the heir to Abraham's promise.
How's that for continuity?
That means he will possess the land of Canaan just like God promised to Abraham.
One day, when Jacob is on his way to the house of his uncle Laban (Remember him? Check out 24:28-60), Esau overhears Isaac's order to Jacob not to marry a foreign wife.
So Esau up and marries Ishmael's daughter Mahalath and with some other wives.
On his way to his uncle Laban's place, Jacob stops for the night. He uses a stone for a pillow and falls asleep.
Now it's gets trippy.
He dreams about some kind of ladder, stairway, or ramp, which rises all the way to heaven. Yep, it's a stairway to heaven.
Still in the dream, messengers of God are going up and down the stairway.
Then it gets even better: the deity appears to Jacob and tells him that land of Canaan will be all his. Muahaha.
Jacob re-names the place Bethel, which means "house of God."
Unlike Abraham and Isaac, who are quiet after God makes big promises, Jacob presses the Lord for more. He more or less says, "I'll tell you what, big dog: if you do all you promised, plus throw in some food and clothes, then I'll worship you as my God right here in Bethel. I'll even throw in 10% of my earnings."
