John Gill Commentary 1 Chronicles 2:10

"And Ram begat Amminadab, and Amminadab begat Nahshon, prince of the children of Judah;" — 1 Chronicles 2:10 (ASV)

Ver. 10-12. And Ram begat Amminadab
Ram is the same with Aram, (Matthew 1:3Matthew 1:4) the genealogy is carried down from him to Jesse in the same order as there, and in (Ruth 4:19–22) only here Nahshon the son of Amminadab is called the prince of the children of Judah ;
which Kimchi and Jarchi say is written for the honour of David, who descended from him; and Salmon his son is here called Salma.
