Mark 12:23-25 King James Version (KJV)
23 In the resurrection therefore, when they shall rise, whose wife shall she be of them? for the seven had her to wife.
24 And Jesus answering said unto them, Do ye not therefore err, because ye know not the scriptures, neither the power of God?
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.
Luke 20:35-36 King James Version (KJV)
35 But they which shall be accounted worthy to obtain that world, and the resurrection from the dead, neither marry, nor are given in marriage:
36 Neither can they die any more: for they are equal unto the angels; and are the children of God, being the children of the resurrection.
