Read Genesis 32:22-31
22 That same night Jacob got up, took his two wives, his two concubines, and his eleven children, and crossed the River Jabbok. 23After he had sent them across, he also sent across all that he owned, 24but he stayed behind, alone.
Then a man came and wrestled with him until just before daybreak. 25When the man saw that he was not winning the struggle, he struck Jacob on the hip, and it was thrown out of joint. 26The man said, “Let me go; daylight is coming.”
“I won’t, unless you bless me,” Jacob answered.
27 “What is your name?” the man asked.
“Jacob,” he answered.
28 The man said, “Your name will no longer be Jacob. You have struggled with God and with men, and you have won; so your name will be Israel.”j
But he answered, “Why do you want to know my name?” Then he blessed Jacob.
30 Jacob said, “I have seen God face to face, and I am still alive”; so he named the place Peniel.k 31The sun rose as Jacob was leaving Peniel, and he was limping because of his hip. 32Even today the descendants of Israel do not eat the muscle which is on the hip joint, because it was on this muscle that Jacob was struck.
Jacob tricked his father Isaac into blessing him instead of Esau after Esau had ceded it to Jacob. Esau was angry and Jacob fled; at this point he is about to return to the land from which he fled and face his brother and take hold of the promised inheritance.
Jacob spends the night before he enters the land wrestling with the angel at Peniel - as he wrestles he asks God to bless what he is about to do.
Jacob wrestled with you as he demanded the blessing that had been promised to him. Today I wrestle with you God as I ask you to bless me. Bless me with the assurance that I am your child - adopted into your family.
