The Oahspe explicitly states that the Ten Commandments of Moses are to be obeyed.
I am Jehovih thy Creator, who brought thee out of the land of Egypt, out of the house of bondage. Thou shalt have no other gods before me.
Thou shalt not make unto thee a graven image, nor 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: thou shalt not bow down thyself unto them, nor serve them; for I Jehovih thy Creator require full worship, visiting the iniquity of the fathers upon the children, upon the third and upon the fourth generation of them that hate me, and showing loving-kindness unto thousands of them that love me and keep my commandments.
Thou shalt not use the name of Jehovih thy Creator in a worthless manner; for Jehovih will not hold him guiltless that taketh his name in vain.
Remember the Sabbath day, to keep it holy. Six days shalt thou labour, and do all thy work; but the seventh day is a Sabbath unto Jehovih: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy man-servant, nor thy maid-servant, nor thy cattle, nor thy stranger that is within thy gates: … Jehovih blessed the sabbath day, and hallowed it.
Honour thy father and thy mother, that thy days may be long in the land which Jehovih giveth thee.
Thou shalt not kill.
Thou shalt not commit adultery.
Thou shalt not steal.
Thou shalt not bear false witness against thy neighbour.
Thou shalt not covet thy neighbour’s house, thou shalt not covet thy neighbour’s wife, nor his man-servant, nor his maid-servant, nor his ox, nor his ass, nor anything that is thy neighbour’s. (Exodus 20:2-17)
