The act of murder is rampant in the Bible. In much of the Bible, especially the Old Testament, there are laws that command that people be killed for absurd reasons such as working on the Sabbath, being gay, cursing your parents, or not being a virgin on your wedding night. In addition to these crazy and immoral laws, there are plenty of examples of God's irrationality by his direct killing of many people for reasons that defy any rational explanation such as killing children who make fun of bald people, and the killing of a man who tried to keep the ark of God from falling during transport. There are also countless examples of mass murders commanded by God, including the murder of women, infants, and children.
Kill People Who Don't Listen to Priests
Anyone arrogant enough to reject the verdict of the judge or of the priest who represents the LORD your God must be put to death. Such evil must be purged from Israel. (Deuteronomy 17:12 NLT)
Kill Nonbelievers
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. (2 Chronicles 15:12-13 NAB)
Kill the Entire Town if One Person Worships Another God
Suppose you hear in one of the towns the LORD your God is giving you that some worthless rabble among you have led their fellow citizens astray by encouraging them to worship foreign gods. In such cases, you must examine the facts carefully. If you find it is true and can prove that such a detestable act has occurred among you, you must attack that town and completely destroy all its inhabitants, as well as all the livestock. Then you must pile all the plunder in the middle of the street and burn it. Put the entire town to the torch as a burnt offering to the LORD your God. That town must remain a ruin forever; it may never be rebuilt. Keep none of the plunder that has been set apart for destruction. Then the LORD will turn from his fierce anger and be merciful to you. He will have compassion on you and make you a great nation, just as he solemnly promised your ancestors. "The LORD your God will be merciful only if you obey him and keep all the commands I am giving you today, doing what is pleasing to him." (Deuteronomy 13:13-19 NLT)
