"And the sons of Simeon: Jemuel, and Jamin, and Ohad, and Jachin, and Zohar, and Shaul the son of a Canaanitish woman; these are the families of Simeon." — Exodus 6:15 (ASV)

And the sons of Simeon, Jemuel, and Jamin, and Ohad, and
Jachin, and Zohar, and Shaul the son of a Canaanitish woman
(See Gill on Genesis 46:10)

these are the families of Simeon ;
who gave rise and name to the several families of that tribe now in Egypt.
