Genesis 32:25-28

25When 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.

26Then the man said, “Let me go, for it is daybreak.” But Jacob replied, “I will not let you go unless you bless me.”

27The man asked him, “What is your name?” “Jacob,” he answered.

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