Passage
`And whoever shall impress thee one mile, go with him two,
`And whoever shall impress thee one mile, go with him two,
Matthew 5:39 but I--I say to you, not to resist the evil, but whoever shall slap thee on thy right cheek, turn to him also the other;
Matthew 5:40 and whoever is willing to take thee to law, and thy coat to take--suffer to him also the cloak.
Matthew 5:41 `And whoever shall impress thee one mile, go with him two,
Matthew 5:42 to him who is asking of thee be giving, and him who is willing to borrow from thee thou mayest not turn away.
Matthew 5:43 `Ye heard that it was said: Thou shalt love thy neighbour, and shalt hate thine enemy;
The verse centers on "whoever", "shall", "impress", "thee", and "mile". It is saying that the verse draws attention to "whoever" and "shall", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 40's "and whoever is willing to take thee..." into verse 42's "to him who is asking of thee...", so "whoever" and "shall" 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 "whoever" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
