Your ^ above ^ post reminded me about under the Constitution of the Mosaic Law there was the Avenger of Blood.Brother. Killing someone can never be assessed just like that. When humans are put to the test, pressed and placed in a desperate situation they might resort to killing for very many reasons. I think I am not capable of killing a human being for any reason. This is the perception of myself that I possess. But I have never been put in a situation so I am only making an assumption.
In that old Hebrew Law the Avenger of Blood applied to the nearest male relative who was under obligation to avenge the blood of one who had been killed - Numbers 35:19.
The reason for the Avenger of Blood is based on or connected back to what was stated to Noah - Genesis 9:5-6.
A proven deliberate murderer was to be put to death - Numbers 35:19-21,31; Deuteronomy 17:8-9.
So, there was a distinction between ' premeditated, deliberate and accidental ', thus ' cities of refuge ' were set up.
- Numbers 35:6-29; Deuteronomy 19:2-13; Joshua 20:2-9.
With the establishment of Christian times, there is No provision for an Avenger of Blood, that duty is for ' Caesar ' to decide. Christians are to lay down the sword - Matthew 26:52.
