Concept:God commanded the total destruction of Amalek as judgment for their hostile opposition to Israel.
Explanation:The command is found in 1 Samuel 15:2–3.
God said, "I have noted what Amalek did to Israel in opposing them on the way when they came up out of Egypt."
Therefore, God instructed Saul to attack Amalek and completely destroy them and all they had.
This punishment was because the Amalekites attacked and opposed the Israelites during their journey from Egypt.
So the reason was not about worship, circumcision, or foreign gods, but their opposition to Israel.
Answer:B. They opposed the Israelites on the way.
