This is exactly the case in our matter. [If] the evil inclination will be victorious over you today [encouraging you to speak] forbidden words, you shall stand and strengthen yourself against him tomorrow, [so that you will emerge] victorious over him. Even if [the evil inclination] will be victorious again, Heaven Forbid, nevertheless, you shall return and strengthen yourself against him to battle him. [If you act in this manner], The Holy One, Blessed is He, will definitely help you [and ensure] that you will also be among the victorious ones, for “[if] one comes to be purified, they help him [from Heaven].” In summary, there should be war between a person and his evil inclination all of one's days. This is, in essence, the intention of our Sages of Blessed Memory [when they instruct]: “A person should always agitate [his good inclination over his evil inclination].” This is also what the pasuk [in “Koheles” (10; 4)] says: “If the spirit of the ruler rises upon you, do not cede your place.”
 See the RaMBa"M’s (Maimonides') “Yad HaChazakah” (Laws of Repentance: 6; 5): “In other words, he will find himself assisted in the matter [of purification, in his quest to overcome his evil inclination].”
 Once a person arouses his good inclination to fight against his evil inclination, it will be easier for him to successfully overcome his inclination to sin.
 The entire pasuk reads, “If the spirit of the ruler rises upon you, do not cede your place, for one who [allows himself to become] weakened leaves great sins.” The pasuk in Hebrew (Koheles: 10; 4) reads:
The Targum (lit. translation, generally from Hebrew to Aramaic) of Yonasan ben Uziel gives the following explanation, “If the spirit of the evil inclination causes you to stumble and strengthens himself [in order to try] to remove you from your good place in which you were accustomed to fulfilling [the Torah], do not leave [your place] for the words of Torah were created as a remedy, causing great sins to be removed and forgotten from this world.”
