Who was Perez?
Perez was one of the twins born to Judah by Tamar, Zerah's brother (Gen 38:29,30).
In the King James Version Mt 1:3 and Lk 3:33, he is called "Phares," the name in 1 Esdras 5:5. He is "Pharez" in the King James Version Gen 46:12; Nu 26:20,21; Ruth 4:12,18; 1 Ch 2:4,5; 4:1; 9:4. In the King James Version and the Revised Version (British and American) 1 Ch 27:3; Neb 11:4,6, he is "Perez."
He is important through the fact that by way of Ruth and Boaz and so through Jesse and David his genealogy comes upward to the Saviour. The patronymic "Pharzite" occurs in Nu 26:20 the King James Version.
