וְהָיָ֗ה כַּאֲשֶׁ֨ר יָרִ֥ים מֹשֶׁ֛ה יָד֖וֹ וְגָבַ֣ר יִשְׂרָאֵ֑ל וְכַאֲשֶׁ֥ר יָנִ֛יחַ יָד֖וֹ וְגָבַ֥ר עֲמָלֵֽק׃
Y sucedía que cuando alzaba Moisés su mano, Israel prevalecía; mas cuando él bajaba su mano, prevalecía Amalec.
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.
