Albert Barnes Commentary Matthew 22:25-28

"Now there were with us seven brethren: and the first married and deceased, and having no seed left his wife unto his brother; in like manner the second also, and the third, unto the seventh. And after them all, the woman died. In the resurrection therefore whose wife shall she be of the seven? for they all had her." — Matthew 22:25-28 (ASV)

There were with us seven brethren. It is probable that they stated a case as difficult as possible. Though no such case might have occurred, it was still conceivable, and in their view, it presented a real difficulty. The difficulty arose because they supposed that substantially the same state of things occurs in the other world as here—namely, that husbands and wives must be reunited. Consequently, they professed they could not see how one woman could be the wife of seven men.
