Jacob
Jacob's generation sees no new items are added to Abraham's Covenant. It does, though, get confirmed. It also sees certain elaborating words, such as North, South, East and West and Community of Nations.
Confirmed to Jacob
Jacob, the son of Isaac and grandson of Abraham, was fleeing the wrath of his brother Esau, when he had a dream. The following is the relevant text:
The place were the dream happens, known as Bethel, but also known as Luz, meant literally, "house of God" and it was a picture of the linkage between the house of God and access to heaven that the stairway represented. 500 years later, this man's descendants would see into heaven again, with their visit to the base of Mount Sinai. 500 years after that they would build a "House of God" with the construction of Solomon's Temple. 1000 years after that, Jesus, "God With Us" would appear in the temple at age 12, and finally, 2000 years after that the age would close.
In this dream God reiterates that Jacob and his descendants are being given the land. The same land that was demarcated by the border with Egypt and the Euphrates river to the east.(Gen 28:13) Jacob's descendants would become as numerous as the "dust of the earth," another reference to an enormous number.(Gen 26:14) Jacob is also told that these people would spread out to the West, East, North, and South providing our first look at the four winds of the skies and providing our first key to this expression in later prophetic literature.(Gen 26:14) Jacob is told that through him all nations will be blessed.
Jacob's name changed
When Jacob finally returns home from his flight to Paddan Aram, he has a restless night where he struggles with an angel. He is told:
Jacob's name, which means "deceiver" is changed to Israel. At this point we see a pattern we last saw with Abraham, where Israel is told that both a nation, and community of nations, will come from him.(Gen 26:11) He is also reminded that kings will come from his body. Again, like Abraham, this is king David, about 920 years later, and Jesus about 1000 years after that. Finally, the land based promise is given to Israel as well.
A curious feature of this story is the way that Jacob pours out wine and oil at this place. Wine is symbolic of Jesus' shed blood, while oil is symbolic of the Holy Spirit of God, or of the anointing that comes through the Holy Spirit. Jacob is reflecting knowledge of that here.
