Rabbeinu Elazar Azkari ZT”L (Sefer Charedim 74) would say:
“Rashi explains that the words 'עקב תשמעון' refer specifically to the ‘lighter’ mitzvos that a person might ‘trample upon with his ankles.’ (דש בעקביו). Such people are held particularly accountable for their misdeeds, as it says in Tehillim, ‘The sins of my ankle will surround me.’ To this, Yirmiyahu Hanavi referred when he said, ‘We will search and examine our ways.’ Meaning, we will search within ourselves and find the less severe sins that we committed, those on which we have trampled. And then, continues the Navi, ‘we will return to Hashem’ - we can now do a proper Teshuvah, because unless the patient knows from what disease he suffers, he has no way of finding a cure.”
R’ Yisroel Baal Shem Tov would say:
“The posuk warns us against arrogance - ‘Your heart will become elevated (haughty) and you will forget Hashem.’ Humility, however, is not enumerated among the Torah’s commandments; if being humble were considered a mitzvah, many Jews would rush to observe it in the most perfect manner possible, taking pride in just how humble they are!”
A Modern-Day Wise Man would say:
“Hashem doesn’t have a Blackberry or an iPhone, but He is my favorite contact. He doesn’t have Facebook, but He is my best friend. He doesn’t have Twitter, but I follow Him nevertheless. He doesn’t have internet, but I am connected to Him. And even though He has a massive communication system, His customer service never puts me on hold!”
