I Timothy 1                                                                                          Exodus 20

for murderers of fathers and murderers of mothers	Honour thy father and thy mother
for manslayers,	Thou shalt not kill.
whoremongers, for them that defile themselves with mankind	Thou shalt not commit adultery.
for menstealers	Thou shalt not steal.
for liars, for perjured persons,	Thou shalt not bear false witness against thy neighbour
if there be any other thing that is contrary to sound doctrine;	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 ass, nor any thing that is thy neighbour's.

 

Why is murderers of Fathers or mothers instead of honour?

Ironside says:

Let me say this, dear young people, you do not have to stab your mother with a knife or a dagger, or strike your father with a club in order to kill them. You can kill them by your willfulness. Many a dear mother has gone down to an early grave heartbroken because of the evil behavior of a loved son or daughter, and many a father has sunk under the awful blow of a son or daughter who turned away from the path of righteousness. We need to remember that murder does not necessarily mean driving a knife into the heart or mixing a cup of poison, but it may consist of anything that breaks a dear one’s health and results in early death. And so the law is given for the lawless, those who would destroy others.
