TRUE STORY
There was this woman, pregnant in her 9th, and it was getting close to shabbos, when she felt something. The husband says go to the hospital she says no, not yet, and a whole long dispute ensues. Time creeps by and she suddenly feels a painful contraction. It was so close to shabbos, but the husband had already made arrangements, so he quickly brought the kids to the babysitter’s house and then rushed his wife to the hospital.
Anyway, she goes into labor, and before you know it the baby pops out, healthy and happily -mazel tov- and all is well! Shortly after, the husband goes back to check up on the kids and arrives late Friday night at his home where he collapses in his bed into a deep sleep.
The next morning in shul he gets an aliyah of course and, because it was Parshas Chayei Sara, he names his new baby, “Rivka”. B”H he had bought food before Shabbos, just in case, and he even gave a little kiddush/L’chaim after davening. Later that day he goes up to visit his wife+baby in the hospital, and she asks him how the Shalom Zachor was. “Shalom Zachor??”
Apparently, the whole ordeal on erev shabbos was in such a rush and so fartumult, he had mistakenly thought the baby was a girl!
So the shaila was brought to R’Elyashiv Shli”ta, what to name the baby boy. He paskened, that since ????? ??????, and they had originally “named” the baby ‘Rivka’, they should name the boy Yitzchok. ????.
It’s brought down in seforim, that when the father names his baby, it is with Ryach Hakodesh, that this name ‘taiches’ up the metziyus and essence of the child. And every father names the child with precisely that name which was ultimately destined for that baby. The couple in the story did not plan to call their baby Yizchok. Originally they had a differnt name. Hashem had to orchestrate this whole rush, bilbul, etc. in order for this baby to end up with its proper name, Yizchok.
