hese are moral precepts added to the
decalogue, and given to the people by God through Moses and Aaron.

But since the things that are evident are the principles whereby we
know those that are not evident, these other moral precepts added to
the decalogue are reducible to the precepts of the decalogue, as so
many corollaries. Thus the first commandment of the decalogue forbids
the worship of strange gods: and to this are added other precepts
forbidding things relating to worship of idols: thus it is written
(Deut. 18:10, 11): "Neither let there be found among you anyone that
shall expiate his son or daughter, making them to pass through the
fire: . . . neither let there by any wizard nor charmer, nor anyone
that consulteth pythonic spirits, or fortune-tellers, or that seeketh
the truth from the dead." The second commandment forbids perjury. To
this is added the prohibition of blasphemy (Lev. 24:15, seqq) and the
prohibition of false doctrine (Deut. 13). To the third commandment

Lev. 19:16: "Thou shalt not stand against the blood of thy neighbor":
likewise the prohibition against hating one's brother (Lev. 19:17):
"Thou shalt not hate thy brother in thy heart." To the sixth
commandment which forbids adultery, is added the prohibition about
whoredom, according to Deut. 23:17: "There shall be no whore among
the daughters of Israel, nor whoremonger among the sons of Israel";
and the prohibition against unnatural sins, according to Lev. 28:22,
23: "Thou shalt not lie with mankind . . . thou shalt not copulate
with any beast." To the seventh commandment which prohibits theft, is
added the precept forbidding usury, according to Deut. 23:19: "Thou
shalt not lend to thy brother money to usury"; and the prohibition
against fraud, according to Deut. 25:13: "Thou shalt not have divers
weights in thy bag"; and universally all prohibitions relating to
peculations and larceny. To the eighth commandment, forbid
