2This is what the LORD of Hosts says: ‘I witnessed what the Amalekites did to the Israelites when they ambushed them on their way up from Egypt.
3Now go and attack the Amalekites and devote to destruction all that belongs to them. Do not spare them, but put to death men and women, children and infants, oxen and sheep, camels and donkeys.’”
— 1 Samuel 15:2-3
