The verse says: "For if you will surely keep all this mitzvah that I command you to do, to love Hashem your God, to walk in all His ways, and to cleave to Him." The Torah is emphasizing the importance of being careful with all the mitzvos, not just some of them. It’s not enough to do things halfway; you have to be diligent in keeping the entire mitzvah. The verse also highlights three key aspects: loving Hashem, walking in all His ways, and cleaving to Him. These are not just actions, but attitudes and approaches to serving Hashem. Loving Hashem means having a deep connection and affection for Him. Walking in all His ways means emulating Hashem’s attributes, and cleaving to Him means striving for a closeness and attachment to Hashem in everything you do.

On the words Shamor Tishmerun, Rashi explains that this is a warning to be very careful, to guard the mitzvos with many safeguards. Specifically, Rashi says to be careful in your learning so that it should not be forgotten. It’s not just about doing the mitzvos, but also about making sure that your Torah learning is protected and retained, so that it doesn’t slip away from you. This means reviewing, setting up reminders, and putting in effort to remember what you’ve learned.

On the phrase Leileches Bechol Derachav, Rashi explains: Just as Hashem is merciful, so too you should be merciful. Just as He does acts of kindness, you should do acts of kindness. The Torah is telling us to imitate Hashem’s ways in our own lives, to develop those same qualities of compassion and kindness in how we interact with others.

On the words Uledovka Vo, Rashi asks: Is it really possible to say this? After all, Hashem is a consuming fire! How can a person cleave to Hashem? Rashi answers: Rather, the way to cleave to Him is by attaching yourself to Torah scholars and wise people. By connecting yourself to those who are close to Hashem, it is considered as if you are cleaving to Him. Hashem counts it for you as if you yourself have become attached to Him.
