Tzav / Command (6:2) This word is deliberately expressed in a form that can refer to both the past and the future. In other words, Hashem's commandments are as applicable today as they were when first promulgated.
The rules governing man's behavior and man's devotion to G-d are timeless. Consequently, our observance of the Torah should not be marked by tired, listless efforts. When we pray, we should not mumble through the prayers out of habit. Rather, we should remember Whom we are addressing, and say each word carefully. The same applies to observance of Shabbos, our Torah learning and other mitzvos. They should not be routine, but rather should be moments of inspiration. We must view the Torah and our prayers as instructions from Hashem on how to act practically. If we do not realize this, and do not actually practice what we say and learn, our words and learning have no meaning or purpose. (Lil'Mode U'Lilamed)
