I do not know why we need to do all this He, He, He stuff. We knew exactly that He was God.
Jacob's name was changed to Israel due to this quality that he possessed. He showed it in this wrestling match with God. All night he struggled. He wrestled with God all night long and would not let go until he received a blessing from God. Jacob was a character. Jacob was unusual. He had a tenacity. He had a fighting spirit, if you will. He had a desire to win, a desire to win in the Hebrew sense.
Now, this episode that we just read marks the turning point in Jacob's life and in his character. He is a changed man after this. This is what his name did. He changed his name and it marked a change in character. He went from heel catcher or supplanter, which is what Jacob means, indicating nefarious, underhanded dealings. If you go and read the chapters before this, he was always trying to trick Laban out of something. And his own brother Esau, his own father. He was a tricky man. But then God changed his name to prevailer, or overcomer with God.
Do you know what Israel actually means if you break it down into its etymological roots? Technically it means "God fights." But the way it has come to be understood was "fights God" or "struggles with God," "strives with God." It is not that he is fighting against Him. He is fighting with him because he wants what God is willing to give him. So he fights God. You have to get your mind into a kind of Hebrew way of thinking. But that is what it comes out as. It is folk etymology because it really should mean "God fights." But the way the Hebrews thought of it after this occurred was that you fight with God, meaning on His side, for Him, not against Him.
But anyway, it is also interesting that when God gives His little spiel about the name Israel, He says, "You prevailed with God and with men." He added, "and with men" in there. Now he did fight with a Man, but this was Jacob's character. Jacob fought with everybody. Jacob tried to prevail with everybody. That was just the kind of man he was. But it shows that Jacob had the same tenacity in overcoming and combating the ideas and plots and temptations of other people, as he did trying to be a warrior of God and overcome the spiritual things. So he was trying to overcome everything.
