What does Matthew 22:25 mean?
A group of Sadducees have approached Jesus with a question (Matthew 22:23–24). Unlike the Pharisees, their intention does not seem to be to get Jesus arrested or accuse Him of blasphemy (Matthew 22:17). Instead, they are presenting a scenario they think illustrates absurdity in the idea of resurrection. This group was known for believing that there was no afterlife or spirit world. Death was the end, according to the Sadducees.In this question, they have pointed to a law in Deuteronomy defining Levirate marriage. This applied to the brother of man who died married but childless. The surviving brother was obligated to marry the widow and have a son with her to continue his late brother's family line (Deuteronomy 25:5–10). The Sadducees suggest a scenario in which there are seven brothers. The first gets married and then dies without having children, leaving his widow to the next brother in line. Then the pattern repeats, resulting in the woman having seven earthly husbands (Matthew 22:26).
When Jesus replies, He will begin by correcting the Sadducees' mistaken beliefs about both marriage and the afterlife (Matthew 22:29–32).
