פירוש על בראשית 21:18

And grasp him with your hand: She would not need to carry him much at all, but he would rather walk with his feet; but you should still grasp him with your hand. And included in [this phrase] is that he would be strengthened from her until she would be strengthened from him. And He further stated about this, for a great nation, etc..

קומי...והחזיקי את ידך, do not let your hand go of him, (do not abandon him) for he will not die by thirst, for I will still make him into a great nation.

Get up: Hence, "Get up and lift the youth," while he is still sick. And afterwards, "grasp him with your hand," and he shall be 'a staff in hand and a hoe for burial' (a source of support in her old age).

Erst stehe auf und nimm wieder den Knaben als starke, nimmer verzweifelnde Mutter; denn nur so bist du der Hülfe Gottes würdig; dann tränke ihn. החזיקי ידך בו, nicht החזיקי בידו was festhalten hieße, sondern: lass deine Hand sich kräftig an ihm bewähren, werde ihm kräftige Stütze und Leiterin, denn ich habe ihm eine große Zukunft bestimmt.
