Bible Verses on Murder

Then Jesus said to him, “Put your sword back into its place, for all those who take the sword will die by the sword....  Matthew 26:52
You shall not murder. Exodus 20:13
But for the cowardly, unbelieving, abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars, their part is in the lake that burns with fire and sulfur, which is the second death.”  Revelation 21:8
Do not seek revenge yourselves, beloved, but give place to God’s wrath. For it is written, “Vengeance belongs to me; I will repay, says the Lord.” Therefore “If your enemy is hungry, feed him. If he is thirsty, give him a drink; for in doing so, you will heap coals of fire on his head.” Do not be overcome by evil, but overcome evil with good. Romans 12:19-21
For this is the message which you heard from the beginning, that we should love one another; unlike Cain, who was of the evil one, and killed his brother. Why did he kill him? Because his works were evil, and his brother’s righteous. Do not be surprised, brothers, if the world hates you. We know that we have passed out of death into life, because we love the brothers. He who does not love remains in death. Whoever hates his brother is a murderer, and you know that no murderer has eternal life remaining in him.   1 John 3:11-15
