Adam Clarke, on Ezek 16:44

“Behold every one that useth a common proverb, shall use this against thee, saying: As the mother was, so also is her daughter.”

“As is the mother, so is her daughter - כאמה בתה keimmah bittah, "As the mother, her daughter." As is the cause, so is the effect. As is the breeding, so is the practice. A silken purse cannot be made out of a swine's ear. What is bred in the bone seldom comes out of the flesh. All such proverbs show the necessity of early holy precepts, supported by suitable example.”
