Rebbe Levi Yitzchak of Berditchev once saw a man who davened so fast that his words were an incomprehensible stream of babbling. Reb Levi Yitzchak approached the Jew after the end of davening and began to speak with him in an equally nonsensical flow of gibberish. When the Jew expressed his lack of understanding, Reb Levi Yitzchak replied, “but this is how you just davened to HaShem!
How do you expect Him to answer your prayers when it is impossible to understand a single word?” The Jew, who didn’t recognize the Rebbe, responded calmly and surely that it wasn’t so. Just as a mother can understand the incoherent babbling of her baby, so too our heavenly Father understands our words even if no one else can! Reb Levi Yitzchak accepted the answer as true and saw it as a defense of Am Yisrael.
