1 Chronicles 27:3

He was a descendant of Perez and chief of all the army commanders for the first month.

Judah’s descendants by their clans:
the Shelanite clan from Shelah;
the Perezite clan from Perez;
the Zerahite clan from Zerah.

But then he pulled his hand back, and his brother came out. Then she said, “You have broken out first!” So he was named Perez.

Judah, your brothers will praise you.
Your hand will be on the necks of your enemies;
your father’s sons will bow down to you.

The one who presented his offering on the first day was Nahshon son of Amminadab from the tribe of Judah.

The military divisions of the camp of Judah with their banner set out first, and Nahshon son of Amminadab was over Judah’s divisions.
