God had already renamed Jacob after their wrestling match (Genesis 32:28). Here He reconfirms the name change. God also reconfirms the covenant:
"And God said to him,
- God tells Jacob to be fruitful and increase in number. As this is not something which Jacob can accomplish on his own, I assume this is God's way of proclaiming to Jacob that He will bless Jacob and his descendants with fruitfulness.
- This promise of fruitfulness recalls the blessing which God pronounced upon Adam and Eve (Genesis 1:28) and also which He renewed to Noah after the flood was over (Genesis 9:1,7).
- Both a nation and a community of nations are supposed to come from Jacob. What does 'a community of nations' mean? It could be that it should read 'a nation, even a community of nations'. At any rate, the idea of greatly increased numbers is clear.
- God explicitly says Jacob and his descendants are given the same land He gave to Abraham and Isaac.
