Eccl 4:9-12 is almost always referenced in the context of marriage, this trully applies but I also see it beyound marriage. We all need that one 'other', we aren't wired to go thru life and stuff alone. ...and the most beautiful part if that one 'other' knows God(third strand which is not easily broken). So for me intentional partnership with God and like mind(friend ,spouse) helps us to navigate thru life challenges safely
