Mark 12:28-31

28And one of the scribes who had come up, and had heard them reasoning together, perceiving that he had answered them well, demanded of him, Which is [the] first commandment of all?

29And Jesus answered him, [The] first commandment of all [is], Hear, Israel: the Lord our 1God is one Lord;

30and thou shalt love the Lord thy 2God with all thy heart, and with all thy soul, and with all thine understanding, and with all thy strength. This is [the] first commandment.

31And a second like it [is] this: Thou shalt love thy neighbour as thyself. There is not another commandment greater than these.
