Mark 12:29-32

29 And Jesus answered him, "The first of all the commandments is: `Hear, O Israel, the Lord our God is one Lord.

30 And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength;' this is the first commandment.

31 And the second is like, namely this: `Thou shalt love thy neighbor as thyself.' There is no other commandment greater than these."

32 And the scribe said unto Him, "Well, Master, thou hast said the truth, for there is one God, and there is none other than He.
