עַ֣ל אֲשֶׁר֩ יִֽהְיֶה־שָּׁ֨ם הָר֤וּחַ לָלֶ֙כֶת֙ יֵלֵ֔כוּ שָׁ֥מָּה הָר֖וּחַ לָלֶ֑כֶת וְהָאוֹפַנִּ֗ים יִנָּשְׂאוּ֙ לְעֻמָּתָ֔ם כִּ֛י ר֥וּחַ הַחַיָּ֖ה בָּאוֹפַנִּֽים׃
Rashi on Ezekiel
there was the will to go It was not necessary to tell them [to go] to this side [or that] because the will of the Holy One, blessed be He, was in the living beings, and the will of the living beings was in the wheels.
