I'm not familiar with the following..
"Go with them twain.".....
What does that mean?
In the time of the Roman occupation of Jerusalem and the Middle East it was custom for a Roman soldier to command a Jewish boy or young man to carry his ‘kit’ for a specified distance. This was like a law which Jesish men/youngmen had to follow. The saying ‘twain’ refers to ‘go the extra mile’, carry the kit for two not just the required one.
I believe it's something like "if a man forces you to walk a mile in his moccasins, walk two miles. That way, you're even further away from him then he wanted, and you've managed to keep his shoes, too."
