Matthew 22:15-33 (ESV)
Paying Taxes to Caesar
15 Then the Pharisees went and plotted how to entangle him in his words. 16 And they sent their disciples to him, along with the Herodians, saying, “Teacher, we know that you are true and teach the way of God truthfully, and you do not care about anyone’s opinion, for you are not swayed by appearances.  17 Tell us, then, what you think. Is it lawful to pay taxes to Caesar, or not?” 18 But Jesus, aware of their malice, said, “Why put me to the test, you hypocrites? 19 Show me the coin for the tax.” And they brought him a denarius.  20 And Jesus said to them, “Whose likeness and inscription is this?” 21 They said, “Caesar’s.” Then he said to them, “Therefore render to Caesar the things that are Caesar’s, and to God the things that are God’s.” 22 When they heard it, they marveled. And they left him and went away.
Sadducees Ask About the Resurrection
23 The same day Sadducees came to him, who say that there is no resurrection, and they asked him a question, 24 saying, “Teacher, Moses said, ‘If a man dies having no children, his brother must marry the widow and raise up children for his brother.’ 25 Now there were seven brothers among us. The first married and died, and having no children left his wife to his brother. 26 So too the second and third, down to the seventh.27 After them all, the woman died. 28 In the resurrection, therefore, of the seven, whose wife will she be? For they all had her.”
29 But Jesus answered them, “You are wrong, because you know neither the Scriptures nor the power of God. 30 For in the resurrection they neither marry nor are given in marriage, but are like angels in heaven. 31 And as for the resurrection of the dead, have you not read what was said to you by God: 32 ‘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.” 33 And when the crowd heard it, they were astonished at his teaching.
