And that to love Him with all one’s heart, with all one’s understanding, and with all one’s strength, and to love one’s neighbor the same way he loves himself, are far more [important] than all the burnt offerings and sacrifices [in the world].”
And the man answered Him, [Deut. 6:5], “You must love the Lord your God with all your heart, with all your soul, with all your strength and with all your mind.” And [Lev. 19:18 says], “[You must love] your neighbor just as [you love] yourself.”
And this is the [greatest] commandment [See Matt. 2:37-38] we have received from Him: [It requires] that the person who [claims to] love God should also love his brother.
