תּלמוד אויף דברים 27:21

Our rabbis taught: Let a man always sell everything that he has and marry the daughter of a talmid ḥakhamim. If he did not find the daughter of a talmid ḥakhamim, let him marry the daughter of the great ones of the generation. If he did not find a daughter of the great ones of the generation, let him marry the daughter of the heads of assemblies. If he did not find a daughter of the heads of assemblies, let him marry the daughter of one appointed over charity. If he did not find the daughter of one appointed over charity, let him marry the daughter of a teacher of children. But let him not marry the daughter of an am-ha’aretz, for they are abominations and their wives are reptiles and about their daughters it is said: Cursed is one who lies with any beast. (Deut 27:21).
