God's Law:
Exo_16:4 Then said the LORD unto Moses, Behold, I will rain bread from heaven for you; and the people shall go out and gather a certain rate every day, that I may prove them, whether they will walk in my law, or no.
Exo_16:28 And the LORD said unto Moses, How long refuse ye to keep my commandments and my laws?
As James also agrees:
Jas_2:11 For he that said, Do not commit adultery, said also, Do not kill. Now if thou commit no adultery, yet if thou kill, thou art become a transgressor of the law.
As Paul also agrees:
Rom_7:7 What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet.
Thus God's law (as called such through all of scripture, from Genesis to Revelation):
Exo 20:1 And God spake all these words, saying,
Exo 20:2 I am the LORD thy God, which have brought thee out of the land of Egypt, out of the house of bondage.
Exo 20:3 Thou shalt have no other gods before me.
Exo 20:4 Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth:
Exo 20:5 Thou shalt not bow down thyself to them, nor serve them: for I the LORD thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me;
Exo 20:6 And shewing mercy unto thousands of them that love me, and keep my commandments.
Exo 20:7 Thou shalt not take the name of the LORD thy God in vain; for the LORD will not hold him guiltless that taketh his name in vain.
Exo 20:8 Remember the sabbath day, to keep it holy.
Exo 20:9 Six days shalt thou labour, and do all thy work:
Exo 20:10 But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates:
Exo 20:11 For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it.
Exo 20:12 Honour thy father and thy mother: that thy days may be long upon the land which the LORD thy God giveth thee.
Exo 20:13 Thou shalt not kill.
Exo 20:14 Thou shalt not commit adultery.
Exo 20:15 Thou shalt not steal.
Exo 20:16 Thou shalt not bear false witness against thy neighbour.
Exo 20:17 Thou shalt not covet thy neighbour's house, thou shalt not covet thy neighbour's wife, nor his manservant, nor his maidservant, nor his ox, nor his a.ss, nor any thing that is thy neighbour's.
Common sense.
