Mar 10:9 What therefore God hath joined together, let not man put asunder.
Alternative: Then, what God put together, let no man separate.
This is a statement about marriage and, in a larger sense, a statement about the limitations on our human capabilities in general. The word that Christ uses for join is based upon the Greek word for "pair" (zeugos) that refers specifically to yoking animals together to do farm work.
The interference is that we are not paired with the opposite sex without any purpose but in order to get a certain type of work done. In this case, that work is creating and raising families. Breaking up the pair has a negative impact on the work intended.
"Joined together" is from zeugnumi (syzeugnymi), which means "to yoke," "to harness," "to bond fast," "join together," "join in wedlock," and "pair."
"Put asunder" is from chôrizô, (chorizo) which means "separate," "divide," and "exclude."
