"and drink their words thirstily": And this is like it is stated (Proverbs 27:7), "A sated person disdains honey, but to a hungry man anything bitter seems sweet." The soul of one who is sated from words of Torah and does not desire them will disdain them - even if they tell him pearls of Torah. But one who is hungry for them, and desires to hear them, will find them sweet in his mouth and will be happy about it - even if he is told something without an explanation - since he knows that it is true, as his teacher said it.
Ramban
WITH ALL THY HEART. In the opinion of the Midrash225Sifre, Va’ethchanan 32; Berachoth 54 a: “With all thy heart — with both your impulses, the good impulse and the evil impulse.” the heart mentioned here is the power of desire, similar to the expressions: Thou hast given him his heart’s desire;226Psalms 21:3. lust not after her beauty in thy heart.227Proverbs 6:25. If so, with all thy soul denotes the intellectual [capacity rather than the sensual capacity of the] soul. Similarly, yet the soul of my lord shall be bound in the bundle of life228I Samuel 25:29. [refers to the rational soul which is immortal]. And according to our Rabbis, who in the Talmud229Berachoth 54 a: “And with all thy soul — even if He take away thy soul,” i.e., even at the sacrifice of your life. derived from this [phrase] that one must submit to death and not violate [the Law, the expanded expression] “with all thy soul” is supplementary,230For, since thy soul by itself indicates that you must suffer martyrdom rather than deny the Law, the question arises, what is signified by the additional word all [‘all’ thy soul], since you cannot speak of half a life? Ramban will offer two answers. for since he said with ‘all’ thy heart … and with ‘all’ thy might [where the intent is to exclude the serving of G-d with only part of the heart’s capacity, or with only part of one’s might or belongings], he also said with ‘all’ thy soul [meaning “your very life,” despite the obvious fact that the command to give “all” rather than “part” of his life is incongruous]. The meaning thereof is that you love Him as your very life, giving up your life with love [for His sake whenever the Law requires you to do so].231See Vol. II, pp. 301-302. Or [another explanation of the word all may be] that suffering or [the loss of body] organs are referred to as “part of the soul,” while martyrdom [death] is termed with ‘all’ thy soul. And Rabbi Abraham ibn Ezra commented: “thy soul means the desire, like: enough ‘k’nafshecha’ (at thine own) pleasure;232Further, 23:25. the full soul loatheth a honey-comb;233Proverbs 27:7. deliver me not over ‘b’nefesh’ (unto the desire of) mine adversaries.234Psalms 27:12. With all thy heart refers to knowledge, this being a surname for the rational spirit since [the heart] is its first resting place, and similarly it is stated, The wise in heart will receive commandments. ”235Proverbs 10:8. Rabbi Abraham ibn Ezra’s interpretation of the expression with all thy heart appears likely from that which he stated, And these words, which I command thee this day, shall be upon thy heart.236Verse 6. This shows that with all thy ‘heart’ refers to the rational soul, for in that case it is possible to say that these words shall be upon your “heart” meaning your rational soul. But if we are to interpret with all thy ‘heart’ as referring to the desires, as explained earlier, then how can it be said that these words shall be upon your “heart” or your desires?
Rashi
we will trample those who rise up against us Heb. נבוס. We will tread and trample our enemies, an expression of (Ezek. 16:6): “wallowing (מתבוססת) in your blood”; (Prov. 27:7), “tramples (תבוס) honeycomb”; (Zech. 10:5), “And they shall be like mighty men, treading (בוסים) the mire of the streets.”
