Exodus 17:8-16 Now Amalek came and fought with Israel in Rephidim. And Moses said to Joshua, “Choose us some men and go out, fight with Amalek. Tomorrow I will stand on the top of the hill with the rod of God in my hand.” So Joshua did as Moses said to him, and fought with Amalek. And Moses, Aaron, and Hur went up to the top of the hill. And so it was, when Moses held up his hand, that Israel prevailed; and when he let down his hand, Amalek prevailed. But Moses’ hands became heavy; so they took a stone and put it under him, and he sat on it. And Aaron and Hur supported his hands, one on one side, and the other on the other side; and his hands were steady until the going down of the sun. So Joshua defeated Amalek and his people with the edge of the sword. Then the LORD said to Moses, “Write this for a memorial in the book and recount it in the hearing of Joshua, that I will utterly blot out the remembrance of Amalek from under heaven.” And Moses built an altar and called its name, The-LORD-Is-My-Banner; for he said, "Because the LORD has sworn: the LORD will have war with Amalek from generation to generation."
Deuteronomy 25:17-19 “Remember what Amalek did to you on the way as you were coming out of Egypt, how he met you on the way and attacked your rear ranks, all the stragglers at your rear, when you were tired and weary; and he did not fear God. Therefore it shall be, when the LORD your God has given you rest from your enemies all around, in the land which the LORD your God is giving you to possess as an inheritance, that you will blot out the remembrance of Amalek from under heaven. You shall not forget.
Judges 6:1-5 Then the children of Israel did evil in the sight of the LORD. So the LORD delivered them into the hand of Midian for seven years, and the hand of Midian prevailed against Israel. Because of the Midianites, the children of Israel made for themselves the dens, the caves, and the strongholds which are in the mountains. So it was, whenever Israel had sown, Midianites would come up; also Amalekites and the people of the East would come up against them. Then they would encamp against them and destroy the produce of the earth as far as Gaza, and leave no sustenance for Israel, neither sheep nor ox nor donkey. For they would come up with their livestock and their tents, coming in as numerous as locusts; both they and their camels were without number; and they would enter the land to destroy it.
1 Samuel 15:2-3 Thus says the LORD of hosts: ‘I will punish Amalek for what he did to Israel, how he ambushed him on the way when he came up from Egypt. Now go and attack Amalek, and utterly destroy all that they have, and do not spare them. But kill both man and woman, infant and nursing child, ox and sheep, camel and donkey.’”
Genesis 36:12 Now Timna was the concubine of Eliphaz, Esau’s son, and she bore Amalek to Eliphaz. These were the sons of Adah, Esau’s wife.
Judges 3:12-13 And the children of Israel again did evil in the sight of the LORD. So the LORD strengthened Eglon king of Moab against Israel, because they had done evil in the sight of the LORD. Then he gathered to himself the people of Ammon and Amalek, went and defeated Israel, and took possession of the City of Palms.
Esther 3:1 After these things King Ahasuerus promoted Haman, the son of Hammedatha the Agagite, and advanced him and set his seat above all the princes who were with him.
