Ezekiel 16:44

Behold, everyone that useth proverbs
That affects a proverbial way of sneaking that is witty and facetious, and has a talent at satirizing and scoffing, as some have had; such were Lucian and others: shall use [this] proverb against thee;
signifying that the sins of the Jews should be well known and exposed, and they should become the subject of the gibes and jeers of men: saying, as [is] the mother, [so is] her daughter;
an ancient and common proverb, used to express a likeness and agreement between persons their nature and disposition, in their behaviour, conduct, and conversation. So the Targum,

``as are the works of the mother, so those of the daughter;''

the mother is the land of Canaan, and the daughter the congregation of Israel, as Kimchi. The Jews were the successors of the old Canaanites, and they imitated them in their practices; and, because both of their succession and imitation, they are called the daughter of them; a bad daughter of a bad mother.
