קוּמָ֤ה יְהוָ֗ה אֵ֭ל נְשָׂ֣א יָדֶ֑ךָ אַל־תִּשְׁכַּ֥ח עניים [עֲנָוִֽים׃]
Ah! Seigneur, lève-toi! Dieu puissant, brandis ta main, n’oublie point les humbles.
Rabbeinu Bahya
כי אשא אל שמים ידי, “For I shall raise My hand to heaven, etc.;” the promise of the redemption of the future is here being confirmed and reinforced with an oath, seeing that the gesture of raising one’s hand towards heaven is typical of someone swearing an oath. We find another example of this in Daniel 12,7 where the promise of the redemption in the future is also accompanied by this gesture. David also used this formula in Psalms 10,12 when he said: “rise, O Lord, raise Your hand.” Not only the promise of the redemption of the future is accompanied by an oath, but even the promise of the redemption from Egypt was accompanied by an oath, seeing that G’d referred to this in retrospect by saying “נשאתי את ידי,“ “I had raised My hand” (Exodus 6,18).
