Exodus 17:10 CPDV

⁸  And Amalek came and fought against Israel at Rephidim.

⁹  And Moses said to Joshua: 'Choose men. And when you go out, fight against Amalek. Tomorrow, I will stand at the top of the hill, holding the staff of God in my hand.'

¹⁰  Joshua did as Moses had spoken, and he fought against Amalek. But Moses and Aaron and Hur ascended to the top of the hill.

¹¹  And when Moses lifted up his hands, Israel prevailed. But when he released them a little while, Amalek overcame.

¹²  Then the hands of Moses became heavy. And so, taking a stone, they placed it beneath him, and he sat on it. Then Aaron and Hur sustained his hands from both sides. And it happened that his hands did not tire until the setting of the sun.
