"That one should not be wise above what is written is well demonstrated in the life of King Solomon. The Torah says that the king whom the Israelites should set over them should not multiply horses to himself, nor wives, in order that he might not cause the people to return to Egypt, and that his heart might not turn away (Deut. 17. 16, 17). 'Then,' argued Solomon, 'since the reason for the paucity of wives and horses is given, I am sure that I can stand proof against these; I can multiply horses and wives and shall not turn away and will not cause my people to return to Egypt.' Unfortunately he was not proof against the prohibitions, as it is recorded against him (in 1 Kings 2. 1-7). And one can also see the wisdom of the Torah in withholding any reason for many commandments it enjoins."
