God changed Jakob's name to Israel

Gen 32:24 Then Jacob was left alone; and a Man wrestled with him until the breaking of day. 25 Now when He saw that He did not prevail against him, He touched the socket of his hip; and the socket of Jacob's hip was out of joint as He wrestled with him. 26 And He said, "Let Me go, for the day breaks." But he said, "I will not let You go unless You bless me!" 27 So He said to him, "What is your name?" And he said, "Jacob." 28 And He said, "Your name shall no longer be called Jacob, but Israel; for you have struggled with God and with men, and have prevailed." 29 Then Jacob asked, saying, "Tell me Your name, I pray." And He said, "Why is it that you ask about My name?" And He blessed him there. 30 And Jacob called the name of the place Peniel: "For I have seen God face to face, and my life is preserved." NKJV
God's finds it amusing  that Jacob asks about his name, since his name is in Jacob's new name, Israel!
