“For I know their imagination how they do even now.”
-Deuteronomy 31:21, JPS 1917 Tanach
“For their evil disposition to which they are yielding today, even before I bring you into the promised land, is known to Me.”
– Targum Yonaton, sefaria.org
G-d knows our proclivity towards aveiros (transgressions). In regard to B’nei Yisrael, He knew that the imagination, i.e., yetzer (inclination) of the people was inclined towards evil. Sforno explains, that the people were about to be brought into the promised land, in order to focus on H’Shem, serving Him through the mitzvot (Psalms 105:44-45); yet, “instead they look forward to gratify their own cravings” (Sforno on Deuteronomy 31:21, sefaria.org) which will lead to an excessive focus on material pleasures, gained from the wealth that H’Shem provides. In other words, they will end up misusing their material goods. By neglecting to focus on H’Shem, after entering the Land, the priorities that were established, “that they might keep His statutes, and observe His laws,” were forgotten (Ps. 105:45).
Although many would like to believe that our natural tendency is to do good, this goes against the grain of understanding. Upon further reflection, we may find that we are inclined to enjoy ourselves, and be entertained by the world, while our efforts to do good are hindered. We may neglect to be kind, considerate, and selfless, unless we seriously strive to do so at all times. As soon as we take our eyes off of H’Shem, especially in this modern world, we might become further distracted, engrossed, and captured by our yetzer hara. Zechirus (vigilance) is of the upmost importance, in order to maintain our sense of deveykus (attachment) to G-d. If we expect to enter into the Promised Land of Olam Haba (the World to Come) with a good place reserved for us there, then, we must keep these points in mind: 1). sur meira, asei tov (eschew evil, do good); 2). show zechirus (vigilance) through constant awareness; and, 3). deveykus (stay connected) to G-d Above, who watches over us from Shomayim (Heaven).
