Exodus 17:8-16

Israel Defeats Amalek

8 cThen Amalek came and fought with Israel at Rephidim. 9So Moses said to dJoshua, “Choose for us men, and go out and fight with Amalek. Tomorrow I will stand on the top of the hill with ethe staff of God in my hand.” 10So fJoshua did as Moses told him, and fought with Amalek, while Moses, Aaron, and gHur went up to the top of the hill. 11Whenever Moses hheld up his hand, Israel prevailed, and whenever he lowered his hand, Amalek prevailed. 12But Moseshands grew weary, so they took a stone and put it under him, and he sat on it, while Aaron and iHur held up his hands, one on one side, and the other on the other side. So his hands were steady until the going down of the sun. 13And jJoshua overwhelmed Amalek and his people with the sword.

14Then the Lord said to Moses, “Write this as a memorial in a book and recite it in the ears of kJoshua, that lI will utterly blot out the memory of Amalek from under heaven.” 15And Moses mbuilt an altar and called the name of it, The Lord Is My Banner, 16saying, “A hand upon the throne
A slight change would yield  upon the banner
of the Lord! oThe Lord will have war with Amalek from generation to generation.”

Numbers 24:18-20

18 pEdom shall be dispossessed;
qSeir also, his enemies, shall be dispossessed.
Israel is doing valiantly.
19And one from Jacob shall exercise dominion
and destroy the survivors of cities!”
20Then he looked on Amalek and rtook up his discourse and said,

Amalek was the first among the nations,
sbut its end is utter destruction.”

Deuteronomy 23:7

7“You shall not abhor an Edomite, for the is your brother. You shall not abhor an Egyptian, because uyou were a sojourner in his land.

Deuteronomy 25:17-19

17 vRemember what Amalek did to you won the way as you came out of Egypt, 18how he attacked you on the way when you were faint and weary, and xcut off your tail, those who were lagging behind you, and he did not fear God. 19Therefore ywhen the Lord your God has given you rest from all your enemies around you, in the land that the Lord your God is giving you for an inheritance to possess, you shall zblot out the memory of Amalek from under heaven; you shall not forget.

1 Samuel 15:2-9

2Thus says the Lord of hosts, ‘I have noted what Amalek did to Israel aain opposing them on the way when they came up out of Egypt. 3Now go and strike Amalek and abdevote to destruction
That is, set apart ( devote) as an offering to the Lord (for destruction); also verses 8, 9, 15, 18, 20, 21
all that they have. Do not spare them, adbut kill both man and woman, child and infant, ox and sheep, camel and donkey.’”

4So Saul summoned the people and numbered them in Telaim, two hundred thousand men on foot, and ten thousand men of Judah. 5And Saul came to the city of Amalek and lay in wait in the valley. 6Then Saul said to aethe Kenites, “Go, depart; go down from among the Amalekites, lest I destroy you with them. afFor you showed kindness to all the people of Israel when they came up out of Egypt.” So the Kenites departed from among the Amalekites. 7 agAnd Saul defeated the Amalekites from ahHavilah as far as aiShur, which is east of Egypt. 8And he took Agag the king of the Amalekites alive ajand devoted to destruction all the people with the edge of the sword. 9 akBut Saul and the people spared Agag and the best of the sheep and of the oxen and of the fattened calves
The meaning of the Hebrew term is uncertain
and the lambs, and all that was good, and would not utterly destroy them. All that was despised and worthless they devoted to destruction.
