Deuteronomy 17:16 "But he shall not accumulate many horses"

Before modern means of transportation were invented, horses were an important asset to man.

Owning many horses was a sign of wealth and power.

The Jewish king must be a leader of noble character.

He should not be concerned with displaying his glamor and wealth.

He certainly does not need to maintain a herd of horses to boast of his power.

Rather, the Jewish king must be concerned with his country's affairs and his people's needs.

Most of all, he should try to guide his subjects in the path of HaShem.

The king may acquire as many horses as he needs for his army and public service. He may own a private horse for his own needs, but he is forbidden to accumulate many horses for grand display.
