On Thursday May 5, the 11th pasuk of Mizmor 119 (The Oral Torah) was posted to the Tehillim section. David declares his devotion to serving Hashem by having committed the Oral Torah to memory. Although he has stored the Torah deep within his heart, he continues to think of that it as “Your spoken word.” That means he visualizes Hashem as continually speaking directly to him. As he performs each mitzvah He recalls Hashem’s instructions relative to that mitzvah because the remembered words are always accessible to his heart. David treasures Hashem’s words and so they are concealed in his heart the way that one might conceal a treasure.
