Genesis 32:29

Wherefore dost thou ask after my name? — What good will it do thee to know that? The discovery of that was reserved for his death — bed, upon which he was taught to call him Shiloh. But instead of telling him his name, he gave him his blessing, which was the thing he wrestled for; he blessed him there, repeated and ratified the blessing formerly given him. See how wonderfully God condescends to countenance and crown importunate prayer? Those that resolve though God slay them, yet to trust in him, will at length be more than conquerors.
