Charles Ellicott Commentary Matthew 1:4

"and Ram begat Amminadab; and Amminadab begat Nahshon; and Nahshon begat Salmon;" — Matthew 1:4 (ASV)

Naasson, or Nahshon, the brother of Elisheba, Aaron’s wife, was the “prince (or captain) of the children” of Judah at the time of the Exodus (Numbers 1:7; Numbers 2:3; 1 Chronicles 2:10). A Jewish legend made him the first to enter the waters of the Red Sea.
