It is written in the Torah "And
the writing was that of G-d's engraved (Haruth) upon the Tablets of
Stone" (Exodus c32, v16).
In Pirqei Aboth (Ethics of the Fathers) it is stated in connection with
the above phrase:
"Read not 'engraved' (Haruth) but 'freedom' (Heruth),
for the only free man is one who occupies himself with the study of the
Torah."
