Duties of the Heart
Therefore, because of this, the prophet (Moshe), peace be upon him, placed it immediately after the unity of G-d, in saying: "Hear, O Israel: The L-ord is our G-d; the L-ord is one; And you shall love the L-ord, your G-d..." (Devarim 6:4), and he exhorted on it, and returned to it many times, as written: "To love the L-ord your G-d, to hearken to His voice, and to cleave to Him" (Devarim 30:20). The meaning of cleaving is: faithful love, and wholehearted devotion, as written: "there is a friend who cleaves closer than a brother"(Mishlei 18:24).
