Mark 12:25-27

25When the dead rise, they will neither marry nor be given in marriage; they will be like the angels in heaven. 26Now about the dead rising—have you not read in the Book of Moses, in the account of the burning bush, how God said to him, ‘I am the God of Abraham, the God of Isaac, and the God of Jacob’ Exodus 3:6 ?

27He is not the God of the dead, but of the living. You are badly mistaken!”
