Tehillim 119:29
דֶּרֶךְ-שֶׁקֶר הָסֵר מִמֶּנִּי וְתוֹרָתְךָ חָנֵּנִי
dereh sheker haser mimeni vetoratcha chaneni
Remove from me the way of falsehood; and favor me with the grace of Your Torah.
Remove from me the way of “sheker” and graciously endow me with Your Torah. For only by adhering to the Torah of “Emet” is it possible to overcome the deceptions and lies of the yetzer hara. In the words of the Gemara:
Thus has HKB”H said to Yisrael: “My son, I have created the yetzer hara and I have created the Torah as its antidote; if you occupy yourselves with the Torah, you will not be delivered into its hand.” (Kiddushin 30b)
A person cannot have knowledge of the Torah so long as he cleaves to "the way of falsehood" - he wastes his time in futile activities. Accordingly, David Hamelech entreats, "Remove from me the way of falsehood; and favor me with the grace of Your Torah."
"Remove from me the way of falsehood" - the empty pursuits of this world - so that I may conduct myself according to the way of the Torah. Let me eat bread with salt, drink water from the cup, and may You "favor me with the grace of Your Torah." Then I will merit to possess the Torah and become refined through her.
David Hamelech pleads further that G-d "remove from me the way of falsehood." Liberate me from the path of arrogance and deception, and "favor me with the grace of Your Torah." Let my study be solely for the sake of attaining Torah truth.
A man will toil in the study of Torah, and come to realize that his earlier views were mistaken. That is his way to possession of truth. But David Hamelech asks for immediate knowledge of the truth. "Remove from me the way of falsehood; and favor me with the grace of Torah" truth, at once.
