Passage
`And there were with us seven brothers, and the first having married did die, and not having seed, he left his wife to his brother;
`And there were with us seven brothers, and the first having married did die, and not having seed, he left his wife to his brother;
Matthew 22:23 In that day there came near to him Sadducees, who are saying there is not a rising again, and they questioned him, saying,
Matthew 22:24 `Teacher, Moses said, If any one may die not having children, his brother shall marry his wife, and shall raise up seed to his brother.
Matthew 22:25 `And there were with us seven brothers, and the first having married did die, and not having seed, he left his wife to his brother;
Matthew 22:26 in like manner also the second, and the third, unto the seventh,
Matthew 22:27 and last of all died also the woman;
The verse centers on "seven", "brothers", "first", "having", "married", "seed", and "left". It is saying that the verse draws attention to "seven" and "brothers", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 24's "Teacher Moses said If any one may..." into verse 26's "in like manner also the second and...", so "seven" and "brothers" belong inside that flow. In Matthew context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "seven" and "brothers" with trust shaped by these words, not by a vague optimism outside the passage.
