Augustine of Hippo : WHAT DOES HIS DAUGHTERS AND DAUGHTERS OF HIS DAUGHTERS MEAN? — And Jacob and all his descendants, and his sons, and his sons' sons, and his daughters, and the daughters of his daughters, went into Egypt . We ask how his daughters and his daughters' daughters can be said, when Scripture states that Jacob had only one daughter. The answer is that, as we said before, daughters can be understood when the granddaughters, just as all the children of Israel designate, in turn, all the people propagated from it. But in this case, when he says the daughters of his daughters, alluding to Dinah only, he puts the plural for the singular, as the singular is also used for the plural. It may also be accepted that the daughters-in-law may have been called daughters. [ — QUESTIONS ON GENESIS, Q. 148 (tr. J. Litteral, draft)
