Genesis 32:26-32 NIV

[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.” [29] Jacob said, “Please tell me your name.” But he replied, “Why do you ask my name?” Then he blessed him there. [30] So Jacob called the place Peniel, saying, “It is because I saw God face to face, and yet my life was spared.” [31] The sun rose above him as he passed Peniel, and he was limping because of his hip. [32] Therefore to this day the Israelites do not eat the tendon attached to the socket of the hip, because the socket of Jacob’s hip was touched near the tendon.
