Matthew 22:31

²⁹ Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God.

³⁰ For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven.

But as touching the resurrection of the dead, have ye not read that which was spoken unto you by God, saying,

³² I am the God of Abraham, and the God of Isaac, and the God of Jacob? God is not the God of the dead, but of the living.

³³ And when the multitude heard this, they were astonished at his doctrine.

Do read the surrounding verses too, because the context often says more than a single verse.
