Another argument to the same effect is, that there is no distinct
command in the law of Moses inculcating the duty; for in Deut. xi. 19 it
is merely said, "And ye shall teach them to your children," a command
which, as it passes refracted through the Rabbinic medium, becomes your
sons, but not your daughters.
