Shemot 17:12-14

Orthodox Jewish Bible

¹² When the hands of Moshe grew heavy, they took an even (stone), and put it under him, and he sat thereon; and Aharon and Chur supported his hands, the one on the one side, and the other on the other side; and his hands held emunah (steady) until bo hashemesh (sunset).

¹³ And Yehoshua disabled Amalek and his army with the edge of the cherev.

¹⁴ And Hashem said unto Moshe, Write this for a zikaron (memorial, remembering) in a sefer, and rehearse it in the ears of Yehoshua; for I will utterly efface the memory of Amalek from under Shomayim.
