Targum su Esodo 17:23

And all the congregation of the sons of Israel journeyed from the desert of Sin by their journeyings according to the word of the Lord, and they encamped in Rephidim, a place where their hands were idle in the commandments of the law, and the fountains were dry, and there was no water for the people to drink.

And the wicked of the people contended with Mosheh, and said, Give us water, that we may drink. And Mosheh said to them, Why contend you with me? and why tempt you before the Lord?

But the people were athirst for water, and the people murmured against Mosheh, and said, Why hast thou made us come up out of Mizraim, to kill us, and our children, and our cattle with thirst ?

And Mosheh prayed before the Lord, saying What shall I do for this people? Yet a very little, and they will stone me.

And the Lord said to Mosheh, Pass over before the people, and take with thee some of the elders of Israel, and the rod with which thou didst smite the river take in thy hand, and go from the face of their murmuring.

Behold, I will stand before thee there, on the spot where thou sawest the impress of the foot on Horeb; and thou shalt smite the rock with thy rod, and therefrom shall come forth waters for drinking, and the people shall drink. And Mosheh did so before the elders of Israel.

And he called the name of that place Temptation and Strife; because there the sons of Israel contended with Mosheh, and because they tempted the Lord, saying, Doth the glory of the majesty of the Lord truly dwell among us, or not?

And Amalek came from the land of the south and leaped on that night a thousand and six hundred miles; and on account of the disagreement which had been between Esau and Jakob, he came and waged war with Israel in Rephidim, and took and killed (some of the) men of the house of Dan; for the cloud did not embrace them, because of the strange worship that was among them.

And Mosheh said to Jehoshua, Choose such men as are strong in the precepts, and victorious in fight; and go, under the Cloud of glory, and set battle in array against the hosts of Amalek. Tomorrow I will stand, prepared with fasting, with the righteous fathers of the chiefs of the people, and the righteous mothers who are like the hills, with the rod with which the miracles have been wrought from before the Lord, in my hand.

And Jehoshua did as Mosheh had bidden him, to wage war with Amalek. And Mosheh, and Aharon, and Hur went up to the top of the height.

And it was, when Mosheh lifted up his hands in prayer, that the house of Israel prevailed; and when he rested his hand from praying, that the house of Amalek prevailed.

And it was that when Mosheh lifted up his hands in prayer, the house of Israel prevailed; and when his hands declined from prayer, Amalek prevailed; and (Israel) fell in the line of battle.

And the hands of Mosheh were heavy, because the conflict was prolonged till the morrow, and the deliverance of Israel was not prepared on that day; and he could not hold them up in prayer; on which account he would have afflicted his soul. And they took a stone, and placed it under him, and he sat upon it; and Aharon and Hur supported his hand, this the one, and that the other; and his hands were outstretched with firmness, (or, fidelity,) in prayer and fasting, until the going down of the sun.

And the hands of Mosheh were lifted up in prayer.

And Jehoshua shattered Amalek, and cut off the heads, of the strong men of his people, by the mouth of the Word of the Lord, with the slaughter of the sword.

And the Lord said unto Mosheh, Write this memorial in the book of the elders that were of old, and these words in the hearing, of Jehoshua, that blotting, I will blot out the memory of Amalek from under the heavens.

And Mosheh builded an altar, and called the name of it, The Word of the Lord is my banner; for the sign which He hath wrought (in this) place was on my behalf.

And he said, Because the Word of the Lord hath sworn by the throne of His glory, that He by His Word will fight against those of the house of Amalek, and destroy them unto three generations; from the generation of this world, from the generation of the Meshiha, and from the generation of the world to come.

And he said, The oath hath come forth from beneath the throne of the Great One, of all the world the Lord; the first king who will sit upon the throne of the kingdom of the sons of Israel, Shaul, the son of Kish, will set the battle in array against the house of Amalek, and will slay them; and those of them that remain will Mardekai and Esther destroy. The Lord hath said by His Word that the memory of Amalek shall perish to the age of ages.
