not daughters only, but sons also, though it may be more daughters than sons, or it may denote remarkable ones, for their beauty or immodesty, or both; and chiefly this is observed for the sake of what follows.

5 Soothly God saw that much malice of men was in [the] earth, and that all the thought of their heart was attentive, either given (over), to evil in all time, (And God saw that there was much malice in people on the earth, and that all the thoughts of their hearts were given over to evil all the time,)
