Genesis 32:27-29

32:27 The man asked him, “What is your name?” He answered, “Jacob.” 32:28 “No longer will your name be Jacob,” the man told him, “but Israel, because you have fought with God and with men and have prevailed.”

32:29 Then Jacob asked, “Please tell me your name.” “Why do you ask my name?” the man replied. Then he blessed Jacob there.
