Tehillim 119:3 af lo faalu avlah bidrachav halakhu
Yes, they do no wrong; they walk in His ways.
"Those who seek" the Torah "with the whole heart" (v119:2), will merit to "do no wrong" any time. All their lives they will "walk in His ways." For the one who comes to purify himself is helped from on high.
"Happy are they whose way is integrity" (v119:1) refers to those who have merited not only to "do no wrong," but also to keep the affirmative mitzvot through actual performance. Thus it says, "Happy are they who" actually "walk in His ways" (ibid.). They not only "depart from evil" (v34:15), but "do good" (ibid.). If, however, they only commit no transgressions and "do no wrong," that is not enough. It is also necessary that "they" actively "walk in His ways."
