Bible Verses About The Amalekites: Discomfited at Rephidim through the intercession of Moses

Moshe said to Y'hoshua, "Choose men for us, go out, and fight with 'Amalek. Tomorrow I will stand on top of the hill with God's staff in my hand."

Y'hoshua did as Moshe had told him and fought with 'Amalek. Then Moshe, Aharon and Hur went up to the top of the hill.

When Moshe raised his hand, Isra'el prevailed; but when he let it down, 'Amalek prevailed.

However, Moshe's hands grew heavy; so they took a stone and put it under him, and he sat on it. Aharon and Hur held up his hands, the one on the one side and the other on the other; so that his hands stayed steady until sunset.

Thus Y'hoshua defeated 'Amalek, putting their people to the sword.
