וַ֠יִּסְעוּ כָּל־עֲדַ֨ת בְּנֵֽי־יִשְׂרָאֵ֧ל מִמִּדְבַּר־סִ֛ין לְמַסְעֵיהֶ֖ם עַל־פִּ֣י יְהוָ֑ה וַֽיַּחֲנוּ֙ בִּרְפִידִ֔ים וְאֵ֥ין מַ֖יִם לִשְׁתֹּ֥ת הָעָֽם׃
이스라엘 자손의 온 회중이 여호와의 명령대로 신 광야에서 떠나 그 노정대로 행하여 르비딤에 장막을 쳤으나 백성이 마실 물이 없는지라
Mishnah Rosh Hashanah
“And it came to pass, when Moses held up his hand Israel prevailed” etc. (Exodus 17:1. Did the hands of Moses wage war or break [Israel’s ability] to wage war? Rather this teaches that as long as Israel would look upwards and subject their hearts to their Father in heaven they prevailed, and if not they fell. Similarly, “Make for yourself a fiery serpent and mount it on a pole. And if anyone who is bitten shall look at it, he shall live” (Numbers 21:8). Did the serpent kill or did the serpent keep alive? Rather, when Israel would look upwards and subject their hearts to their Father in heaven, they were healed, and if not their [flesh] would melt away. A deaf-mute, a lunatic and a minor cannot cause others to fulfill their religious obligation. This is the general principle: one who is not himself obligated in the matter cannot perform it on behalf of others.
