Charles Spurgeon Commentary Genesis 32:26-29

"And he said, Let me go, for the day breaketh. And he said, I will not let thee go, except thou bless me. And he said unto him, What is thy name? And he said, Jacob. And he said, Thy name shall be called no more Jacob, but Israel: for thou hast striven with God and with men, and hast prevailed. And Jacob asked him, and said, Tell me, I pray thee, thy name. And he said, Wherefore is it that thou dost ask after my name? And he blessed him there." — Genesis 32:26-29 (ASV)

And he said, Let me go, for the day breaketh. And he said, I will not let thee go, except thou bless me. And he said unto him, What is thy name? And he said, Jacob. And he said, Thy name shall be called no more Jacob, but Israel: for as a prince hast thou power with God and with men, and hast prevailed. And Jacob asked him, and said, Tell me, I pray thee, thy name. And he said, Wherefore is it that thou dost ask after my name? And he blessed him there.

He would not gratify Jacob's curiosity concerning his name, but he gave him the blessing that he craved. This was just as our Divine Master acted when his disciples inquired of him concerning the times and seasons; he told them it was not for them to know what the Father had retained in his own power; but Christ added, what was much better for them, Ye shall receive power, after that the Holy Ghost is come upon you. He will not tell us all we want to know, but he will give us all we need to have. What a wise and prudent Lord is ours!
