“For example Yaakov Avinu was 84, and never used a Shadchan. So if you are 84 and have not sinned all your life like Yaakov then you can do it without a Shadchan.”
Who says that was the reason why he never needed a shadchan? Maybe if like Yaakov, you leave your parents’ home and live on your own, you should not need a shadchan.
“Moshe Rabbeinu did use a Shadchan, this is clear, when Yisro said ‘I am giving you my daughter as a wife’.”
He met Yocheved at the well (similar to Yaakov Avinu and Rochel), before he met Yisro. Yisro was his FIL not his shadchan.
“Shimshon never used a Shadchan, but Talmud Sotah reproaches him for this (he went after his eyes so the philistines gorged his eyes), we can learn from this if you don’t use a Shadchan and follow your eyes you will end up marrying a goy (Samson married philistine Delilah).”
Hoo boy! I never used a shadchan and I guarantee you neither my husband, my daughter-in-law, nor my son-in-law are goyim. Shimshon was a man who was nichshal, and for that he was punished, not for not having a shadchan. If he had a shadchan, he wouldn’t have lusted after Delilah?????
“Dovid Hamelech never used a Shadchan with Bat Sheva as Talmud Shabbos says she was destined to him from the Six Days of Creation.”
As are all our zivugim before we are even born.
“Rabbi Akiva dated Rochel without a Shadchan (this was when he was a Am Haaretz).”
A shadchan would NEVER have redt that shidduch, so B”H no shadchan was involved, or we would all be the poorer for not experiencing R’ Akiva’s gadlus and example of mesiras nefesh.
