And when [the Man] saw that He did not prevail against [Jacob], He touched the hollow of his thigh; and Jacob's thigh was put out of joint as he wrestled with Him.
That is why to this day the Israelites do not eat the sinew of the hip which is on the hollow of the thigh, because [the Angel of the Lord] touched the hollow of Jacob's thigh on the sinew of the hip.
Thus says the Lord, the Holy One of Israel, and its Maker: Would you question Me about things to come concerning My children, and concerning the work of My hands [would you] command Me?
All of you must keep awake (give strict attention, be cautious and active) and watch and pray, that you may not come into temptation. The spirit indeed is willing, but the flesh is weak.
