שָׁרְשִׁ֣י פָת֣וּחַ אֱלֵי־מָ֑יִם וְ֝טַ֗ל יָלִ֥ין בִּקְצִירִֽי׃
מײַן װאָרצל װעט זײַן אָפֿן צום װאַסער, און דער טױ װעט נעכטיקן אױף מײַן צװײַג.
Rashi
My root will be open etc. All this I was saying to myself, that my root would not dry up, and my branches would not die, like (above 14:9), “and it will produce a branch (קציר).” They are יונקות, tender branches of a tree.
