Mark 12:18-34 ESV
And Sadducees came to him, who say that there is no resurrection. And they asked him a question, saying, “Teacher, Moses wrote for us that if a man’s brother dies and leaves a wife, but leaves no child, the man must take the widow and raise up offspring for his brother. There were seven brothers; the first took a wife, and when he died left no offspring. And the second took her, and died, leaving no offspring. And the third likewise. And the seven left no offspring. Last of all the woman also died. In the resurrection, when they rise again, whose wife will she be? For the seven had her as wife.”
Jesus said to them, “Is this not the reason you are wrong, because you know neither the Scriptures nor the power of God? For when they rise from the dead, they neither marry nor are given in marriage, but are like angels in heaven. And as for the dead being raised, have you not read in the book of Moses, in the passage about the bush, how God spoke to him, saying, ‘I am the God of Abraham, and the God of Isaac, and the God of Jacob’? He is not God of the dead, but of the living. You are quite wrong.”
And one of the scribes came up and heard them disputing with one another, and seeing that he answered them well, asked him, “Which commandment is the most important of all?” Jesus answered, “The most important is, ‘Hear, O Israel: The Lord our God, the Lord is one. And you shall love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.’ The second is this: ‘You shall love your neighbor as yourself.’ There is no other commandment greater than these.” And the scribe said to him, “You are right, Teacher. You have truly said that he is one, and there is no other besides him. And to love him with all the heart and with all the understanding and with all the strength, and to love one’s neighbor as oneself, is much more than all whole burnt offerings and sacrifices.” And when Jesus saw that he answered wisely, he said to him, “You are not far from the kingdom of God.” And after that no one dared to ask him any more questions.
