This week's portion is called Ekev (since). Moses continues preparing the Jewish people for their entry into the Land of Israel, explaining certain commandments and mentioning others that had not yet been transmitted, such as the blessing after meals. Additionally, the second section of the Shema appears in this parashah.
Our sages explain that the order of the three sections of the Shema is due to the fact that the first part speaks of accepting God as the Lord, the second mentions accepting God's commandments, and the third (despite appearing earlier in the Torah text) speaks of Tzitzit, a Mitzvah that applies only during the day (while the other concepts mentioned above apply both day and night, which is why they precede it).
One of the central ideas of the second section of the Shema, which is in this week's Torah portion, is the concept of reward and punishment. God rewards the observance of mitzvot and punishes their neglect. Today, the punishments are not applied exactly as they appear in the Torah due to the absence of the Sanhedrin (High Court), the lack of a Temple, and other issues. However, the system remains in effect, and both the reward and the punishment are spiritual. In fact, according to Jewish mystical tradition, the rewards mentioned in the Torah are purely spiritual. Even when the Torah speaks of "long life," "inheriting the land," and other expressions that seem to have material applications, it is still referring to spiritual life and the spiritual land, Gan Eden.
Hasidic thought revealed a new dimension of depth in the Torah. Every phrase takes on a new meaning, and, even more strikingly, a meaning that applies to each person's spiritual service, motivating them to improve their qualities and draw closer to God.
In the middle of the description of the reward and punishment system, the Torah says (Deuteronomy 11:16-17): "Be careful, lest your heart turn away […] and you quickly lose sight of the good land that God is giving you.".
Regarding this last verse, the Alter Rebbe, Rabbi Shneur Zalman of Liadi (1745-1812), taught that, on one hand, a person's will and desire to serve God are identified with the Land of Israel. The Hebrew word for land, eretz, is related to the word ratzon, which means will. A person must work on themselves to "lose" the "quick" attitude of their will ("land") to serve God.
In other words, every moment, every mitzvah, should be seized and experienced to the fullest, not cut short or rushed. A simple example of this idea is the Shabbat prayer: since people have more time on Shabbat, as they have no obligations, our sages added a series of psalms to the prayer. The purpose of these psalms is for the person to appreciate and perceive divine greatness in detail, something that is not possible during the week due to work obligations.
So, according to this interpretation, the verse is saying that we must remove (eliminate) the swiftness, the speed, from the earth, from our service to God. And the same applies to all situations in life: every process, every step of growth, takes a certain amount of time, and that time should be enjoyed and used wisely in order to bring the growth process to its fullest potential. Even in painful situations, may God save us, we must know that every moment of that experience has a purpose and should be used for personal refinement.
