He chose men,  with beards, who were Jewish, and excluded those of professions which were not represented by the men He did choose.  Were all of them or only some of them married?  What is significant?  None of the above or all of the above.

There is picking and choosing going on about what was significant about those whom Our Lord chose as His closest companions.  What we know of His choices fits the time, culture, circumstances in which He came.  And what we know is what men remembered as significant and chose to write down decades later.  

There is a lot of reading into the choices Jesus made that is people with particular points of view seeking to make it appear their points of view were also those of Jesus.  And no recognition that Jesus came into a particular culture and at a particular point in history.  Since Jesus never rode in a car or flew in an airplane, what makes it okay that we do now?
