Well, it may not have been murder---the illegal taking of a human life---no laws being in effect, but it was certainly paedocide (the killing of children).
Is this suppose absolve god of killing them?
The children were incorrigibly wicked?
Sorry, but making up stuff doesn't cut it. It actually makes you a liar, liar pants on fire.
Forcing women into marriage and having sex with them amounts to rape. In order to avoid rape there has to be uncoerced agreement, which we know damn well was seldom if ever the case. Rape isn't mitigated by a forced marriage.
I'd ask you to visit post 25, but figure you wouldn't bother, so I've copied/pasted the relevant parts.
In 2 Samuel 12:11-12 (CEB) it says
11 “This is what the Lord says: I am making trouble come against you from inside your own family. Before your very eyes I will take your wives away and give them to your friend, and he will have sex with your wives in broad daylight. 12 You did what you did secretly, but I will do what I am doing before all Israel in the light of day.”
Think these poor wives were willing sex objects? Hardly, which would make them victims of rape.
And in Zechariah 14;1-2 (CEB) it says
The day of the Lord
14 A day is coming that belongs to the Lord,
when that which has been plundered from you will be divided among you.
2 I will gather all the nations to Jerusalem for the battle,
the city will be captured,
the houses will be plundered,
and the women will be raped.
Half of the city will go forth into exile,
but what is left of the people won’t be eliminated from the city.
So, obviously rape isn't off the list at all. God does allow it. Even demands it,
