A.T. Robertson Commentary Luke 20:27

"And there came to him certain of the Sadducees, they that say that there is no resurrection;" — Luke 20:27 (ASV)

There is no resurrection (αναστασιν μη εινα). Accusative and infinitive with negative μη in indirect assertion. The Sadducees rally after the complete discomfiture of the Pharisees and Herodians. They had a stock conundrum with which they had often gotten a laugh on the Pharisees. So they volunteer to try it on Jesus. For discussion of details here see on Mt 22:23-33; Mr 12:18-27. Only a few striking items remain for Luke.
