1 Samuel (15:3), God said to Saul:
"Now go, attack the Amalekites, and totally destroy all that belongs to them. Do not spare them; put to death men and women, children and infants, cattle and sheep, camels and donkeys."

the Puritans used this passage when they wanted to get rid of the Native American tribes. Catholics used it against Protestants, Protestants against Catholics. "In Rwanda in 1994, Hutu preachers invoked King Saul's memory to justify the total slaughter of their Tutsi neighbors,"

This fall, more than 100,000 American public school children, ranging in age from four to 12, are scheduled to receive instruction in the lessons of Saul and the Amalekites in the comfort of their own public school classrooms. The instruction, which features in the second week of a weekly "Bible study" course, will come from the Good News Club, an after-school program sponsored by a group called the Child Evangelism Fellowship (CEF).
