Keep Davening in Hebrew
In a letter to the government, the Rav argued that Hebrew must remain the language of the services.
When proposals arose to move the services into German, Rav Mordechai wrote to the authorities and argued for keeping Hebrew. His reasoning was practical as well as spiritual. A Jew who davens in the language of his surroundings will have little reason to learn the holy language, and a Jew who does not know it will gradually lose his connection to Scripture itself. The words of tefillah are not just a vehicle for the thoughts of the heart, in his view, but the doorway through which the whole of the Torah is entered. If that door is closed, learning will fade, and the knowledge of Tanach with it. Many years afterward, at the 1845 conference of rabbanim in Frankfurt, the same case for keeping Hebrew was made again, and it confirmed his warning that without it Scripture would slowly be forgotten.

Pick one tefillah you say every day, perhaps Modeh Ani, Ashrei or the first paragraph of Shema, and spend five minutes this week learning what each Hebrew word means. Say it again slowly, understanding it. If your Hebrew is limited, use a translation alongside the text and learn two or three new words each day. Davening in Hebrew is a living bond with generations before you, and every word you understand strengthens that bond for yourself and for those who see you daven.
