Mark 12:28-34
And one of the scribes came, and having heard them reasoning together, and perceiving that he had answered them well, asked him, Which is the first commandment of all?And Jesus answered him, The first of all the commandments[ is], Hear, O Israel; The Lord our God is one Lord: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.And the second[ is] like,[ namely] this, Thou shalt love thy neighbour as thyself. There is none other commandment greater than these.And the scribe said unto him, Well, Master, thou hast said the truth: for there is one God; and there is none other but he:And to love him with all the heart, and with all the understanding, and with all the soul, and with all the strength, and to love[ his] neighbour as himself, is more than all whole burnt offerings and sacrifices.And when Jesus saw that he answered discreetly, he said unto him, Thou art not far from the kingdom of God. And no man after that durst ask him[ any question].
Matthew 22:34-40
But when the Pharisees had heard that he had put the Sadducees to silence, they were gathered together.Then one of them,[ which was] a lawyer, asked[ him a question], tempting him, and saying,Master, which[ is] the great commandment in the law?Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.This is the first and great commandment.And the second[ is] like unto it, Thou shalt love thy neighbour as thyself.On these two commandments hang all the law and the prophets.
