Hear, O Israel, the L-rd is our G‑d, the L-rd is One.
And thou shalt love the L-rd thy G‑d with all thy heart, and with all
thy soul, and with all thy might. And these words that I command thee this
day, shall be upon thy heart. And thou shalt teach them diligently unto
thy children, and thou shalt talk of them when thou sittest in thy house,
and when thou walkest by the way, and when thou liest down and when thou
risest up. And thou shalt bind them for a sign upon thy hand, and they
shalt be for frontlets (totafot) between thine eyes. And thou shalt
write them upon the doorposts (mezuzoth) of thy house, and upon thy gates.
(Deuteronomy VI, 4‑9).
And it shall come to pass, if ye shall hearken diligently onto My
commandments which I enjoin upon thou this day, to love the L-rd your G‑d
and to serve Him with all your heart and with all your soul, that I will
give the rain of your land in its season, the former rain and the latter
rain, that thou mayest gather in thy corn, and thy wine, and thine oil.
And I will give grass in thy fields for thy cattle, and thou shalt eat and
be satisfied. Take heed to yourselves, lest your heart be deceived, and ye
turn aside and serve other gods, and worship them; and the anger of the
Lord be kindled against you, and He shut up the heaven, so that there
shall be no rain, and the ground shall not yield her fruit; and ye perish
quickly from off the good land which the L‑rd giveth you. Therefore, shall
ye lay up these My words in your heart and in your soul; and ye shall bind
them for a sign upon your hand, and they shall be for frontlets (totafot)
between your eyes. And ye shall teach them your children, talking of them,
when thou sittest in thy house, and when thou walkest by the way, and when
thou liest down, and when thou risest up. And thou shalt write them upon
the doorposts (mezuzoth) of thy house, and upon thy gates; that your days
may be multiplied, and the days of your children, upon the land which the
L-rd swore onto your fathers to give them, [for as long] as the days of
the heavens about the earth.” (Deuteronomy XI, 13-21).
