Mark 12:29-31

Yehoshua has answered: the first is: Hear Israel Hashem our G-d Hashem echad; and you (SG) you shall love have the L-rd your G-d with your whole heart, and with your whole soul, and with your whole understanding, and with your whole power. (Deuteronomy 6, 4-5.) the second (command) is: you (SG) you shall love have your neighbor as you yourself. (Leviticus 19, 18) not other command greater than the these is not there.
