Chasidut zu Bereschit 32:5

"And he commanded them saying" (Gen. 32:5) - the explanation of "commanded" is that it is an expression of alacrity, as in "The expression of command always implies alacrity" (Rashi on Lev. 6:2 and Kiddushin 29a:13) meaning, that the tzadik brings out his words from his holy mouth in holiness and alacrity, to such a degree that they become so strong [that] "to say" meaning that this thing will be said immediately, that Esav will have a turn about [and become] his brother, because obviously it is not appropriate to make this thing the essence of tefilah. Only through the Clinging that exists in the rest of the tzadik's tefilah, and the tzadik's words from the clean and lucid thoughts, immediately this word comes to fruition, that [the tzadik's] enemies make peace.
