“Who is the ‘friend who sticks closer than a brother’?”
The line comes from a section of Proverbs attributed to King Solomon. Many Hebrew proverbs state a truism twice in slightly different words. Other times, the two statements contrast. Either way, the first line usually provides a clue to the interpretation of the second, or vice versa. In interpreting proverbs or poetry, I try to let whichever part is easiest to understand guide me through the bit that’s a little tougher.
In this case … hoo boy, good luck.
