Passage
Master, Moses wrote unto us, If a man’s brother die, and leave his wife behind him, and leave no children, that his brother should take his wife, and raise up seed unto his brother.
Master, Moses wrote unto us, If a man’s brother die, and leave his wife behind him, and leave no children, that his brother should take his wife, and raise up seed unto his brother.
Mark 12:17 And Jesus answering said unto them, Render to Caesar the things that are Caesar’s, and to God the things that are God’s. And they marvelled at him.
Mark 12:18 Then come unto him the Sadducees, which say there is no resurrection; and they asked him, saying,
Mark 12:19 Master, Moses wrote unto us, If a man’s brother die, and leave his wife behind him, and leave no children, that his brother should take his wife, and raise up seed unto his brother.
Mark 12:20 Now there were seven brethren: and the first took a wife, and dying left no seed.
Mark 12:21 And the second took her, and died, neither left he any seed: and the third likewise.
The verse centers on "master", "moses", "wrote", "brother", "leave", "wife", and "behind". It is saying that the verse draws attention to "master" and "moses", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 18's "Then come unto him the Sadducees which..." into verse 20's "Now there were seven brethren and the...", so "master" and "moses" belong inside that flow. In Mark context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "master" and "moses" with trust shaped by these words, not by a vague optimism outside the passage.
