Kill Followers of Other Religions
While the Israelites were camped at Acacia, some of the men defiled themselves by sleeping with the local Moabite women. These women invited them to attend sacrifices to their gods, and soon the Israelites were feasting with them and worshiping the gods of Moab. Before long Israel was joining in the worship of Baal of Peor, causing the LORD's anger to blaze against his people. The LORD issued the following command to Moses: "Seize all the ringleaders and execute them before the LORD in broad daylight, so his fierce anger will turn away from the people of Israel." So Moses ordered Israel's judges to execute everyone who had joined in worshiping Baal of Peor. Just then one of the Israelite men brought a Midianite woman into the camp, right before the eyes of Moses and all the people, as they were weeping at the entrance of the Tabernacle. When Phinehas son of Eleazar and grandson of Aaron the priest saw this, he jumped up and left the assembly. Then he took a spear and rushed after the man into his tent. Phinehas thrust the spear all the way through the man's body and into the woman's stomach. So the plague against the Israelites was stopped, but not before 24,000 people had died. (Numbers 25:1-9 NLT)
Murder
At the customary time for offering the evening sacrifice, Elijah the prophet walked up to the altar and prayed, "O LORD, God of Abraham, Isaac, and Jacob, prove today that you are God in Israel and that I am your servant. Prove that I have done all this at your command. O LORD, answer me! Answer me so these people will know that you, O LORD, are God and that you have brought them back to yourself." Immediately the fire of the LORD flashed down from heaven and burned up the young bull, the wood, the stones, and the dust. It even licked up all the water in the ditch! And when the people saw it, they fell on their faces and cried out, "The LORD is God! The LORD is God!" Then Elijah commanded, "Seize all the prophets of Baal. Don't let a single one escape!" So the people seized them all, and Elijah took them down to the Kishon Valley and killed them there. (1 Kings 18:36-40 NLT)
Kill All of Babylon
"Go up, my warriors, against the land of Merathaim and against the people of Pekod. Yes, march against Babylon, the land of rebels, a land that I will judge! Pursue, kill, and completely destroy them, as I have commanded you," says the LORD. "Let the battle cry be heard in the land, a shout of great destruction". (Jeremiah 50:21-22 NLT)
Micah Kills a Whole Town
Then, with Micah's idols and his priest, the men of Dan came to the town of Laish, whose people were peaceful and secure. They attacked and killed all the people and burned the town to the ground. There was no one to rescue the residents of the town, for they lived a great distance from Sidon and had no allies nearby. This happened in the valley near Beth-rehob.Then the people of the tribe of Dan rebuilt the town and lived there. They renamed the town Dan after their ancestor, Israel's son, but it had originally been called Laish. (Judges 18:27-29 NLT) (Note that God approves of this slaughter in verse 6.)
