Genesis 35:10-12
10 God said to him, “Your name is Jacob, but you will no longer be called Jacob; your name will be Israel.” So he named him Israel.
11 And God said to him, “I am God Almighty; be fruitful and increase in number. A nation and a community of nations will come from you, and kings will come from your body.
12 The land I gave to Abraham and Isaac I also give to you, and I will give this land to your descendants after you.”
