Хасидус к Шмот 17:2

וַיָּ֤רֶב הָעָם֙ עִם־מֹשֶׁ֔ה וַיֹּ֣אמְר֔וּ תְּנוּ־לָ֥נוּ מַ֖יִם וְנִשְׁתֶּ֑ה וַיֹּ֤אמֶר לָהֶם֙ מֹשֶׁ֔ה מַה־תְּרִיבוּן֙ עִמָּדִ֔י מַה־תְּנַסּ֖וּן אֶת־יְהוָֽה׃

Посему люди стремились с Моисеем и говорили: 'Дай нам воды, чтобы мы могли пить.' И сказал им Моисей: 'Зачем стремиться со мной? для чего вы пытаетесь Господа?'

For the main element of life-force is received from prayer, as it is written, "A Prayer to the God of my Life." Therefore, a person must pray with all of their power, for when a person prays with all of their power, and puts their power into the letters of the prayer, then their power is renewed there, in the aspect of "they are renewed in the morning, great is your faithfulness." For faith is [also] prayer, as it is written, "and his hands were steady," which [Onkelos] translates as, "they were spread in prayer."
