Passage
And they twaine shalbe one flesh: so that they are no more twaine, but one flesh.
And they twaine shalbe one flesh: so that they are no more twaine, but one flesh.
Mark 10:6 But at the beginning of the creation God made them male and female:
Mark 10:7 For this cause shall man leaue his father and mother, and cleaue vnto his wife.
Mark 10:8 And they twaine shalbe one flesh: so that they are no more twaine, but one flesh.
Mark 10:9 Therefore, what God hath coupled together, let not man separate.
Mark 10:10 And in the house his disciples asked him againe of that matter.
The verse centers on "twaine", "shalbe", and "flesh". It is saying that the verse draws attention to "twaine" and "shalbe", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 7's "For this cause shall man leaue his..." into verse 9's "Therefore what God hath coupled together let...", so "twaine" and "shalbe" 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 "twaine" and "shalbe" with trust shaped by these words, not by a vague optimism outside the passage.
