וַיָּבֹ֜אוּ עַד־נַ֣חַל אֶשְׁכֹּ֗ל וַיִּכְרְת֨וּ מִשָּׁ֤ם זְמוֹרָה֙ וְאֶשְׁכּ֤וֹל עֲנָבִים֙ אֶחָ֔ד וַיִּשָּׂאֻ֥הוּ בַמּ֖וֹט בִּשְׁנָ֑יִם וּמִן־הָרִמֹּנִ֖ים וּמִן־הַתְּאֵנִֽים׃
Sie kamen zum Thale Eskol und schnitten von dort eine Rebe mit einer Weintraube ab und trugen sie zu zweien auf einer Bahre; sie nahmen auch von den Granatäpfeln und von den Feigen.
Rashi on Numbers
זמורה (lit., AND THEY CUT DOWN FROM THENCE) A BRANCH [AND ONE CLUSTER OF GRAPES] — i.e. a vine branch with a cluster of grapes hanging from it (not as the text might suggest, that they cut a branch and they cut also a cluster of grapes),
Rabbeinu Bahya
Siftei Chakhamim
With a cluster of grapes hanging from it. [The meaning is] as if Scripture had written “from there they cut off a branch with one cluster of grapes” rather than interpreting [that they cut off] “a branch” by itself and a “cluster” by itself; for if so why would they have cut off the branch at all, since it had no fruit.
