But it was thou, a man mine equal, my guide, and mine acquaintance.
But it was thou, a man mine equal - literally, 'a man according to my rank' or 'estimation.' Friendship binds only equals; these it unites in the closest bonds. The Septuagint and Muis take it 'one like-minded' (Philippians 2:20).
My guide - my counselor; as Ahithophel was to David (1 Samuel 15:12; 1 Samuel 16:23).
Mine acquaintance - whom I acquainted with my secret feelings; as Jesus did toward Judas, along with the rest of the twelve (John 15:15).
