² Thus says the Lord of hosts: I will punish the Amalekites for what they did in opposing the Israelites when they came up out of Egypt.^(A)

¹⁷ “Remember what Amalek did to you on your journey out of Egypt,^{(A) 18} how he attacked you on the way, when you were faint and weary, and struck down all who lagged behind you; he did not fear God. ¹⁹ Therefore when the Lord your God has given you rest from all your enemies on every hand, in the land that the Lord your God is giving you as an inheritance to possess, you shall blot out the remembrance of Amalek from under heaven; do not forget.^(B)

²⁰ Then he looked on Amalek and uttered his oracle, saying,

Amalek Attacks Israel and Is Defeated

⁸ Then Amalek came and fought with Israel at Rephidim.^{(A) 9} Moses said to Joshua, “Choose some men for us and go out; fight with Amalek. Tomorrow I will stand on the top of the hill with the staff of God in my hand.”^{(B) 10} So Joshua did as Moses told him and fought with Amalek, while Moses, Aaron, and Hur went up to the top of the hill. ¹¹ Whenever Moses held up his hand, Israel prevailed, and whenever he lowered his hand, Amalek prevailed. ¹² But Moses’s hands grew heavy, so they took a stone and put it under him, and he sat on it. Aaron and Hur held up his hands, one on either side, so his hands were steady until the sun set. ¹³ And Joshua defeated Amalek and his people with the sword.

¹⁴ Then the Lord said to Moses, “Write this as a remembrance in a book and recite it in the hearing of Joshua: I will utterly blot out the memory of Amalek from under heaven.”^{(C) 15} And Moses built an altar and called it, The Lord is my banner. ¹⁶ He said, “A hand upon the banner of the Lord!^[a] The Lord will have war with Amalek from generation to generation.”

³⁴ No longer shall they teach one another or say to each other, “Know the Lord,” for they shall all know me, from the least of them to the greatest, says the Lord, for I will forgive their iniquity and remember their sin no more.^(A)
