I've been reading the answers given in this similar question or even in the "duplicate question" but they don't respond to my question which is slightly different. I'm not wondering if Killing is legit or not, but WHY God commanded to kill in the Old Testament.
This is a very common question asked by atheist as a way to show Bible inconsistencies and I believe the question and answers given in the previous questions are not exactly answering that.
I'm wondering why, in the first moment, God in the Old Testament was commanding to kill other people when in the New Testament killing is totally forbidden and Jesus never commanded it in any case.
It sounds like two different Gods: the aggressive one and the pacifist.
Some quotes from the old Testament commanding to kill are the following ones:
Leviticus 20:13 NAB
"If a man lies with a male as with a women, both of them shall be put to death for their abominable deed; they have forfeited their lives."
2 Chronicles 15:12-13 NAB
They entered into a covenant to seek the Lord, the God of their fathers, with all their heart and soul; and everyone who would not seek the Lord, the God of Israel, was to be put to death, whether small or great, whether man or woman.
Exodus 22:17 NAB
You should not let a sorceress live.
Leviticus 20:27 NAB
A man or a woman who acts as a medium or fortuneteller shall be put to death by stoning; they have no one but themselves to blame for their death.
