'Resurrection' in the Bible

On that day Sadducees (those who say that there is no resurrection) came to him. They asked him,

In the resurrection therefore, whose wife will she be of the seven? For they all had her."

For in the resurrection they neither marry, nor are given in marriage, but are like God's angels in heaven.

But concerning the resurrection of the dead, haven't you read that which was spoken to you by God, saying,

and coming out of the tombs after his resurrection, they entered into the holy city and appeared to many.
