Hashem Helps Us Praise Him

The Siddur HaShlah explains the pasuk in Tehillim that says to “open your mouth wide and He will fill it” to mean that one should open his mouth and say many praises to Hashem. One should not think that he is not worthy of doing so or that he doesn’t know how to do it properly because Hashem promises that He will “fill our mouths” with the proper words to say. Hashem will help us praise Him. He will teach us how to glorify Him properly. When one makes the effort to daven to Hashem, He gives him the words to praise Him properly, as Chazal say (Yoma 38B): When one comes to purify himself, he receives Divine assistance.
