here’s a joke…would we make a shidduch with anyone from the torah
Yitzchak Avinu : Well his grandfather made idols, and there was all that nastiness with Lot and his half brother is an arab.
Yakov Avinu: His great grandfather made idols, his brother went of the derech, his mother comes from a very treyfe family, and he wasn’t shomer negiah with rachel imenu before they were married and he spent a lot of time with his uncle who’s mamash a rasha.
Dovid HaMelech: Descendants from a geyoret, not our kind of people. Sure a few generations have gone but all things being equal shouldn’t we look for someone with a more jewish backround.
Shlomo HaMelech: See above.. And his mother’s marriage was very dubious, he is rich though but the yichus and family backround is very tricky.
