Genesis 9:6
4 “But you must not eat meat with its life (that is, its blood) in it. 5 For your lifeblood I will surely exact punishment, from every living creature I will exact punishment. From each person I will exact punishment for the life of the individual since the man was his relative. 6 “Whoever sheds human blood, by other humans must his blood be shed; for in God’s image God has made humankind. 7 “But as for you, be fruitful and multiply; increase abundantly on the earth and multiply on it.” 8 God said to Noah and his sons,
Revelation 13:10
8 and all those who live on the earth will worship the beast, everyone whose name has not been written since the foundation of the world in the book of life belonging to the Lamb who was killed. 9 If anyone has an ear, he had better listen! 10 If anyone is meant for captivity, into captivity he will go. If anyone is to be killed by the sword, then by the sword he must be killed. This requires steadfast endurance and faith from the saints. 11 Then I saw another beast coming up from the earth. He had two horns like a lamb, but was speaking like a dragon. 12 He exercised all the ruling authority of the first beast on his behalf, and made the earth and those who inhabit it worship the first beast, the one whose lethal wound had been healed.
Notes and References
"... [the Hebrew Bible] is the literature of a whole nation, not of a small sect, and therefore naturally covers more areas of ethical concern, whereas the New Testament tends to concentrate on matters of personal morality and of relationships within the Christian community. One obvious difference is that the Hebrew Bible has a lot of material on the taking of human life, since it has to legislate for a nation that had some kind of judicial system. There is nothing like this in the New Testament: early Christians did not have the power to try legal cases or to inflict penalties on offenders. The Hebrew Bible has an attitude to the taking of human life that is unusual in the ancient world. All murder (i.e. deliberate homicide) is a capital offence. This differs from the norms in some of the surrounding cultures, as can be seen from the Code of Hammurabi. Here the penalty for murder depends on the relative social status of the victim and the murderer: killing a slave is not treated as seriously as killing a nobleman. It follows that not all murderers are executed. But one could argue that the Hebrew Bible’s requirement that execution, not a fine, is the only acceptable penalty for murder, regardless of the status of the people involved, represents a higher valuation of human life. This may be connected with the idea that humans are made ‘in the image and likeness of God’ (Genesis 1:26–27), and this principle is explicitly stated in the clearest reference to the death penalty for murder, Genesis 9:6 ..."
