Mark 10:8 Meaning and Commentary

Mark 10:8

And the twain shall be one flesh
This is the remaining part of the citation out of ( Genesis 2:24 ) ; (See Gill on Matthew 19:5);

so then they are no more twain; but one flesh;
as Adam and Eve were both by creation and marriage: and so two persons, a man and woman, being lawfully married together, become one flesh, or "one body", as the Arabic and Persic versions render the phrase; and therefore the wife is to be loved by the husband as his own body, and from whom there should be no separation, until death, but in case of adultery; (See Gill on Matthew 19:6).

Mark 10:8 In-Context

6 But in the beginning, at the time of creation, "God made them male and female,' as the scripture says.

7 "And for this reason a man will leave his father and mother and unite with his wife,

8 and the two will become one.' So they are no longer two, but one.

9 No human being must separate, then, what God has joined together."

10 When they went back into the house, the disciples asked Jesus about this matter.
