Mark 12:28

25 For when they shall rise from the dead, they neither marry, nor are given in marriage; but are as angels in heaven.

26 But as touching the dead, that they are raised; have ye not read in the book of Moses, in [the place concerning] the Bush, how God spake unto him, saying, I [am] the God of Abraham, and the God of Isaac, and the God of Jacob?

27 He is not the God of the dead, but of the living: ye do greatly err.

28 And one of the scribes came, and heard them questioning together, and knowing that he had answered them well, asked him, What commandment is the first of all?

29 Jesus answered, The first is, Hear, O Israel; The Lord our God, the Lord is one:

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.

31 The second is this, Thou shalt love thy neighbor as thyself. There is none other commandment greater than these.
