Mark 12:28

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

26 And as touching the dead, that they rise: have ye not read in the book of Moses, how in the bush 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 the God of the living: ye therefore do greatly err.

28 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?

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 neighbour as thyself. There is none other commandment greater than these.
