Luke 20:33

Therefore in the resurrection whose wife of them is she? for seven had her to wife.

In Luke 20:33 the Sadducees press their denial of the resurrection with a test case in which seven brothers had successively each been married to the same woman, demanding whose wife she would be if the dead were raised. Their question rests on the assumption that people will resume earthly marriages and relationships after the resurrection. They use that assumption to make bodily resurrection appear absurd.

It is an artful question intended to entangle Christ. He answers plainly and intelligently, bringing precious light to the people.
