²⁴ So Jacob was left alone, and a man wrestled with him till daybreak. ²⁵ When the man saw that he could not overpower him, he touched the socket of Jacob’s hip so that his hip was wrenched as he wrestled with the man. ²⁶ Then the man said, “Let me go, for it is daybreak.”

But Jacob replied, “I will not let you go unless you bless me.”

²⁷ The man asked him, “What is your name?”

“Jacob,” he answered.

²⁸ Then the man said, “Your name will no longer be Jacob, but Israel, because you have struggled with God and with humans and have overcome.”
