L’Exode 17:11 Targum : Targum Jonathan & Targum Jerusalem

וְהָיָ֗ה כַּאֲשֶׁ֨ר יָרִ֥ים מֹשֶׁ֛ה יָד֖וֹ וְגָבַ֣ר יִשְׂרָאֵ֑ל וְכַאֲשֶׁ֥ר יָנִ֛יחַ יָד֖וֹ וְגָבַ֥ר עֲמָלֵֽק׃

Or, tant que Moïse tenait son bras levé, Israël avait le dessus; lorsqu’il le laissait fléchir, c’est Amalec qui l’emportait.

Targum Jonathan on Exodus

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.

Targum Jerusalem

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.
